 specimens I described, but is well marked in three from 

 Santa Catharina {Ehrhardt) received in lUlO.

Crenicichla smitaremensis, Ilaseman, Ann. Carnegie Mus. vii. 1911, 

 p. 354, pi. Ixii. tig. 1. 



The slight differences from C, macrophfhalmus noted by 

 Haseman are due to the small size of his specimens as 

 compared with Heckel's type. 



9. Crenicichla wallacii, Regan, 1905. 



? Crenicichla macrophthahna, Haseman, Ann. Carnegie Mus. vii. 1911, 

 p. 353. 



10. Crenicichla nanus, sp. n. 



Depth of body 5| in the length, length of head 3|. Snout 

 a little shorter than diameter of eye, which is o?^ in tlie length 

 of head ; interorbital width 5. Nostril nearly equidistant 

 from eye and end of snout. Maxillary not extending to 

 below eye; anterior teeth forming 5 or 6 series in botli jaws. 

 10 gill-rakers on lower part of anterior arch. 65 scales in a 

 longitudinal series below lateral line, 6 from first and 2 from 

 last dorsal spine to lateral line, 3 between upper and lower 

 lateral lines. Lateral line 19-23 + 10-11. Dorsal XX- 

 XXI 11 ; last spine a little more than ^ the length of head. 

 Anal III 8. Pectorals g, pelvics ^ tlie lengtli of head. 

 Caudal peduncle longer than deep. A dark lateral band 

 from snout througli eye to end of caudal fin ; a small ocellus 

 on upper part of base of caudal. 



Two specimens, 40 and 45 mm., from British Guiana, 

 received from Prof. Eigenmann as C. loallacii, from which 

 they differ especially in the lower dorsal spines. It is 

 doubtful whether all the specimens recorded by Eigenmann 

 as C. loallacii (Mem. Carnegie Mus. v. 1912, p. 517) belong 

 to this species. 



11. Crenicichla notophthalmus, sp. n. 



Depth of body 5 to 6 in the length, length of head 3,^. 

 Snout as long as or a little shorter than diameter of eye, 

 which is 3| in the length of head ; interorbital width 5 to 6. 

 Nostril nearly equidistant from eye and end of snout.
