Description of the specimen. — This species agrees with P. fronto in 

 the general habit ; its body is compressed, highest above the oper- 

 culum, tapering posteriorly ; the upper and anterior profile of the 

 head forms a quarter of a circle. The height of the body equals the 

 length of the head, and is one-third of the total length ; the eye is 

 very small, situated nearer to the end of the snout than to that of 

 the operculum, and more remote from the lower profile than from 

 the upper. The cleft of the mouth is of moderate width, slightly 

 oblique, and with the jaws nearly equal in length. The teeth are 

 minute, forming bands ; there is a small patch of teeth on the vomer. 

 There is a very small tubercle midway between the eye and the end 

 of the snout, but there is no nasal opening. The branchial aperture 

 is obliquely situated ; it is very wide, extending on to the symphysis 

 of the lower jaw ; no slit behind the fourth giU. The doi-sal fin is 

 perfectly continuous, extending from the snout to the middle of the 

 caudal fin ; the first spine is very short, the second is the strongest, 

 enveloped in a thick membrane (both are situated before the vertical 

 from the eye) ; the second and the third are the longest, one-half 

 the height of the body ; the following become gradually somewhat
