This fish is closely allied to E. gyrimis, but is said to be distinguished by having the 

 height of the body only one-sLxth or one-seventh of the total length'; lower parts of 

 the body with numerous whitish spots and streaks. 



From the Pacific side of the Isthmus. 



108. Eleotris seminuda. 



Gunth. Proc. Zool. Soc. 1864, p. 24. 



D. 7|11. A. 9. 



The head and the trunk are naked ; the tail is covered with small scales ; head 

 depressed, broader than high, flat above, its length being two-sevenths of the total. 

 Snout rather obtuse, longer than the eye, with the lower jaw somewhat prominent; the 

 cleft of the mouth extends to below the anterior margin of the orbit. Teeth in the 

 upper jaw in a narrow band ; the lower has four somewhat larger and recurved teeth in 

 front ; they appear to form a single series ; palate toothless. None of the fin-rays are 

 prolonged ; the pectoral does not quite extend to the origin of the second dorsal ; 

 ventral much shorter than pectoral, its inner ray is the longest, the others gradually 

 decreasing in length outwards ; caudal fin rounded. Brown, with numerous Avell- 

 defined white cross stripes on the head as well as on the body ; vertical fins black. 



Although there is only a single example, 20 lines long, in the collection, the charac- 

 ters of this species are so well marked that I have not hesitated to describe it. 



109. Amblyopus brevis. 



Giinth. Proc. Zool. Soc. 1864, p. 151. 



D. 6|15. A. 15. 



The height of the body is one-eightli of the total length (without caudal) ; the length 

 of the head two-ninths. Eyes minute. Jaws with a series of longish, widely set teeth. 

 Caudal fin black. 



One specimen, 3 inches long, was found on the Pacific coast of Panama by Messrs. 

 Dow and Salvin. 



The specimen being young, I abstain from gi™ig a detailed description. In its 

 dentition it agrees with A. sagitta from California, and therefore it would belong to the 

 subgenus Tyntlastes (Proc. Zool. Soc. 1862, p. 194). The scales must have been very 

 thin and deciduous, and do not appear to be very small, at least not on the hinder part 

 of the body. The ventral is much longer than the pectoral, and tlie caudal longer than 

 the head. 



' According to the figure it is higher.
