 i. Adult : skeleton. South America. Presented by Sir E. Schom- 



biirgk. 



The skeleton of this species does not essentially differ from that of 

 other Gobies, the elongate form of the body not being produced by 

 an increase of the number of the vertebrae, but by the single ver- 

 tebrae being prolonged. The length of the abdominal portion of the 

 vertebral column is to that of the caudal as 1 : 1*4, 



h. Caudal fin rounded, not elongate, 

 aa. Canine teeth none.

Scales rather small. The height of the body is rather more than 

 the length of the head, and one-fifth of the total. Snout of mode- 

 rate extent, somewhat convex. Dorsal fins lower than the body ; 

 caudal roiuaded. Olive, with subqiiadrangular brownish spots ; a 

 pair of whitish spots on the base of the caudal fin, and a single one 

 below the eye. All the fins, except the ventrals, with series of

Twenty-two series of scales between the second dorsal and the 

 anal fins. The height of the body is contained five times and two- 

 thirds in the total length, the length of the head four times. Head 

 depressed ; eyes prominent ; snout of moderate extent ; cleft of the 

 mouth oblique, with the lower jaw longest; teeth of the outer series 

 enlarged. The width of the interorbital space is less than that of 

 the orbit. Eye of moderate size. Dorsal fins close together ; the 

 second is higher than the first, but rather lower than the body : 

 the venti'als do not reach to the vent : caudal rounded. Brownish- 

 yeUow, with numerous ii-regular black spots ; fins brown-spotted.
