440 DE. GtJNTHER ON THE FISHES OF CENTRAL AMERICA. 



sides ; a black ocellus edged with rosy in the middle of the side, another larger one on 

 tlu- base of the ninth and tenth dorsal rays, and one or two small ones on the side of 

 the tail. Belly covered with round brown spots; caudal with ovate black spots, 

 arranged m three transverse series ; all the other fins with similar spots. 



One specimen, 2^ inches long, was found by Capt. Dow on the Pacific coast of Panama. 



96. Amtennarius tenuifilis. 

 D. 3/12. A. 7. P. 10. 



Allied to A. bigibhus. Skin rough, the spines being exceedingly fine ; anterior dorsal 

 spine (tentacle) much longer than the second, and tapering into a fine point ; second 

 quite free, conical; third entirely covered by the skin, forming a slight protuberance. 

 Rose-coloured, with black markings which are most crowded and confluent on the 

 middle parts of the length of the fish, less so on the head and thorax, leaving the nape 

 and back of the trunk nearly immaculate ; the markings form irregular concentric 

 streaks on the thorax, and larger patches on the body; a deep-black band across the 

 caudal and anal fins. 



One specimen, 2\ inches long, was found by Dr. Seemann, walking on the reefs outside 

 the city of Panama. 



103. Eleotris maculata (B1.). 

 This species attains to a large size; Mr. Salvin collected specimens 11 inches long 

 at Huamuchal. Such large examples have, of course, the eye comparatively smaller 

 than younger ones ; and having also a deeper body, the number of series of scales 

 between the origin of the second dorsal and the anal is increased by the addition of 

 smaller scales. On such a large example Mr. Gill has founded his Bormitator microph- 

 thahnus, Proc. Ac. Nat. Sc. Philad. 1863, p. 170. 



106. Eleotris longiceps. 

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



D. 6 I ij. A. j^. L. lat. 66. 



Vomerine teeth in a broad subcrescentic band, which is more than half as broad as 

 that of the intermaxillaries. Thirty-six series of scales between the occiput and the 

 anterior dorsal fin ; twenty between the origin of the posterior and the anal. The 

 height of the body is nearly one-half of the length of the head, which is more than one- 

 third of the total (without caudal). The maxillary extends to below the middle of the 

 eye; teeth cardiform. Caudal fin obtusely rounded, one-sixth of the total length. 

 Brownish black, marbled with brown and black ; fins with roundish blackish spots. 



This species differs from the others (which have been referred to the division of 

 Philyimus) in having a comparatively longer head. One specimen, 8 inches long, was 

 given to Mr. Salvin by Capt. Dow, who found it in the Lake of Nicaragua.
