 of Fortaleza, Ceard (October); Lagoa Parangaba, near Fortaleza 

 (May); roadside pool, Sobral, Ceard (October); pool at Jatoba, 

 Pernambuco (March); Acude Alorada Bonita, near Lavras, Ceard; 

 Acude Grande near Maranguape, Ceard (November); Acude Serrote 

 near Maranguape, Ceard (May); Acude Marizinho, Lavras, Ceard 

 (August) ; pool, Sobral Ceard. 



Recorded distribution. — Sumatra (Sars, 1903). 



Subfamily Cyprinae 



Valves commonly pigmented with occasional marginal tubercles or 

 crenulations. Second antennae with natatory setae usually not 

 reaching beyond tips of the terminal claws. Third maxillary process 

 with, one or two or sometimes all setae spinelike and either toothed 

 or smooth. Second thoracic leg with a beaklike terminal claw and a 

 long reflexed seta. Furcal ramus well developed, with two claws and 

 two setae or rudimentary. 



Genus PELOCYPRIS Klie 



Pelocypris Klie, Zool. Anz., vol. 128, p. 85, 1939. 



Shell of firm consistency with numerous long, heavy, blunted 

 spines on the anterior and posterior borders. Height about half the 

 length. Rather broad forms when viewed from above. Surface of 

 valves with an intricate pattern of small brownish spots. Second 

 antennae with well-developed natatory setae which extend con- 

 siderably beyond the tips of the terminal claws. First thoracic leg 

 with a long curved terminal claw. Second leg with one short and one 

 long seta. Furca well developed with the dorsal seta longer than the 

 subterminal claw. 



Remarks. — This striking genus was first described by Klie from 

 northeastern Brazil. Its characteristics are very similar in many 

 ways to those of Ilyocypris, but the presence of heavy spines on the 

 valves and the entirely different second thoracic leg show clearly that 

 it belongs to a different genus.
