Retroculus acherontos, a new species of cichlid fish (Teleostei) from the Rio Tocantins basin.
Retroculus acherontos is described from the Rio Tocantins basin, Brazil. It is distinguished from all congeners by the presence of a nuchal hump in large specimens, an irregular black blotch located on the middle of the anterior soft dorsal-fin rays, fewer pectoral-fin rays (15-16), a deeper body, a convex ventral profile, a more transversely convex ventral surface of the body, and by chest scales similar in size to the scales on the side. An expanded diagnosis for the genus Retroculus is provided.This invention relates to a seal device for use in a tire pressure-adjusting device for adjusting the pressure of a tire of an automobile from the driver's seat.
The inflation pressure of a tire of an automobile greatly influences not only safety, such as the braking and the steering, but also the life of the tire and the ride of the automobile. For this reason, recently, there has been developed a tire pressure-adjusting device for properly adjusting the tire pressure in accordance with the running condition from the room of the automobile.
In a conventional tire pressure-adjusting device, compressed air is supplied from an air supply source via an air pipe to an air passage in an axle case, and the compressed air is further fed from this air passage
