eigenmann: the FRESHWATER FISHES OF BRITISH GUIANA 379 



Seven specimens, 33-36 mm. Tumatumari. (C. M. Cat. No. 1299a-c; 

 I. U. Cat, No. 11787.) 



Sixteen specimens, 35-44 mm. Creek below Potaro Landing. (C. M. Cat. 

 No. 1300a-e; I. U. Cat. No. 11788.) 



Two specimens, 30 mm. Rupununi Pan. (C. M. Cat. No. 1301.) 



Fifteen specimens, 30-36 mm. Wismar. (C. M. Cat. No. 2062a-//; I. U. 

 Cat. No. 12252.) 



Twenty-four specimens, 24-39 mm. Rockstone sand-bank. (C. M. Cat. 

 No. 2063a-Z; I. U. Cat. No. 12253.) 



This species is found in small woodland streams, contrasting thus with the 

 species of Gasteropelecus, which are pelagic (in the larger rivers) in their habits. 



Head about 4; depth about 2; D. 10; A. 27-29; scales 30, twelve to fifteen 

 pores in the lateral line, the line broken after the sixth scale; eye 3 in the distance 

 from tip of chin to end of opercle. 



Easily recognized by its markings, for which see figure. 



The types of G. strigatus in the British Museum are in a bad state of preser- 

 vation, but are undoubtedly identical with G. fasciatus of Garman. 



Gasteropelecus Gronow. 



Gasteropelecus Gronow, Mus. Ichth., II, 1756, 7. — Gunther, Catalogue, V, 1864,
