user108: What Buddhist distinction is made between "awareness" and "consciousness"?
I view "mindfulness" as a purposeful application of awareness.
However, I am at a loss for a clear distinction between awareness and consciousness.

user3551: Before differentiating between Consciousness and Awareness we'd first have to define what Consciousness is and what Awareness is on its own.Try to answer these questions How do you know that your aware? What's the evidence?Where do you find your awareness,your knowing?Not What you know but what's it like to be knowing?What's it like to be aware?
Can you sense how some experiences goes beyond words,concepts and intellectualised ideas.
And can only be described by our relationship or attachments to it.
So what is awareness?Maybe Awareness is A, Maybe Awareness is B, Maybe Awareness just IS.
I have to add that consciousness is an aggregate and is biased.It may well be the result of clinging to awareness.Seeing it as My awareness.But i still think its difficult to pin down.

user-1: It's difficult to translate "buddhist terms" that refer to aspects and functions of the mind to western equivalents. Moreover, since buddhist psychology is quite sophisticated and detailed, it would be hard to draw distinction over loosely defined concepts (such as "consciousness", "awareness" and "mindfulness" under quotes). 
For example, there are many terms that carry some form of awareness used in the suttas, but with different nuances. One of them is viññāṇa (which is actually sixfold). Another, which may overlap with our understandings of "consciousness" or "awareness" is sañña. Sati, which is usually translated as "mindfulness" is also a very technical term in buddhism.
Generally, these 3 terms (there are a few others) not only refer to distinct processes of the mind, but also may have different meanings across the suttas themselves. Furthermore, they also appear to overlap in some cases.
A few questions (eg. this and this) have been asked here about the definitions of some of these terms and differences. One book that explores this subject in depth is Identity and Experience: The Constitution of the Human Being According to Early Buddhism.

user8157: "Awareness" is an English word used by Westerners that (to my knowledge) does not really exist in the terminology of Pali Buddhism. 
I agree with the view that "mindfulness" ('sati') is a purposeful application of awareness or consciousness. 'Sati' means to 'remember' or 'bring to/keep in mind'. 
The Pali uses the word 'anupassi' ('continous seeing') when referring to being aware of meditation objects or uses the word 'sampajjana' ('ready wisdom') when referring to knowing clearly what is going on in meditation.
Westerners like using the word 'awareness' but I do not know a Pali equivalent. 

user143: Here is a short passage from What the Buddha Taught by Dr. Walpola Rahula that discusses how consciousness is different than perception. I'm not sure if this answers your question, but I found the example given helpful to my own understanding of consciousness.

It should be clearly understood that consciousness does not recognize an
  object. It is only a sort of awareness-awareness of the presence of an object. When
  the eye comes in contact with a colour, for instance blue, visual consciousness arises
  which simply is awareness of the presence of a colour: but it does not recognize that
  it is blue. There is no recognition at this stage. It is perception (the third Aggregate
  discussed above) that recognizes that it is blue. The term 'visual consciousness' is a
  philosophical expression denoting the same idea as is conveyed by the ordinary
  word 'seeing'. Seeing does not mean recognizing. So are the other forms of
  consciousness.
