14. Apistogramma amoenus, Cope. 



Depth of body 2j to 2^ in the length, length of. head 8. 

 Snout a little shorter than diameter of eye, which is 3£ to ."< .1 

 in length of head; interorbital width 3§ to 4. Maxillary 

 extending to below anterior edge of eye ; lower jaw § length 

 of head ; least depth of prseorbital ^ to ? diameter of eye ; 

 cheek with 3 or 4 series of scales ; 2 or 3 gill-rakers of outer 

 series below angle, of first arch. 23 scales in a longitudinal 

 series ; 12 or 13 in upper lateral line, 5 or 6 in lower. 

 Dorsal XV 6-7 ; spines subequal from the fifth, the last ^ 

 the length of head or a little more. Anal III 6 ; third spine 

 scarcely shorter than last of dorsal. Pectoral nearly as long 

 as head, almost or quite reaching origin of anal ; pelvics 

 extending to second or third anal spine. Caudal rounded. 

 Caudal peduncle deeper than long. Traces of cross-bars and 

 of a lateral band ; a dark spot at base of caudal ; posterior 

 part of soft dorsal and anal and middle of caudal barred with 

 spots. 



Two specimens, 50 and 55 mm. in total length. 



A. to niatum, Giinth., seems to be known only from the 

 type, 60 mm. in total length, from the Cupai; it differs from 

 A. amoenus in the shorter snout and larger eye (diameter ^ 

 length of head), larger mouth (maxillary to below anterior 

 ^ of eye; lower jaw nearly^ length of head), and higher 

 dorsal spines, increasing in length to the last which is quite 

 § the length of the head. 



A. per tense is the species usually known as H. tceniatum ; 

 it is close to A. amoenus, but when specimens of the same 

 size are compared it differs in the larger eye (^ length of 

 head) and more slender form (depth 3 in the length). 

 A. agassizii is distinguished by the pointed caudal fin.

This well-known Ethiopian species must now be included 

 in the fauna of British India. Mr. Bainbrigge Fletcher has 



sent us specimens from Coimbatore, South India.
