KNTOMOSTRACA FROM CEYLON. 339 



antepenultimate joint of the right antenna has a hyaline mem- 

 brane and a short outwardly-turned hook (fig. 12), The fifth 

 leg (fig. 13) on the right side has two small hyaline processes on 

 the second basal joint ; the endopodite is longer than the first 

 joint of the exopodite. The first joint of the exopodite is pro- 

 duced laterally into a pointed process and bears on its posterior 

 face a large hyaline process (fig. 14). The second joint of the 

 exopodite has the spine, which is usually lateral and distal in 

 position, inserted on the posterior face near the base of the joint. 

 Length 1"75 mm.

ISToTODROMAS ocuLATA Sars. (PI. III. fig. 15.) 



Tank by Lady Horton's Drive. 



This species differs very little from JV. entzi Daday, bei no- 

 somewhat smaller and with difierent markings. In dorsal view 

 it is seen that N. entzi is much wider behind than in front, 

 whereas in N. oculata the outline is an almost regular oval 

 (fig. 15). 



Strandesia (Cypris) vittata Sars. 



Common in Peradeniya. pond. 



My specimens agree in all respects with Sars's description, 

 with the exception that they do not show the coloured bands 

 mentioned by him, the absence of whicli is possibly due to the 

 preservative. The curious " lop-sided " appearance in end view 

 is very characteristic. Previously I'ecorded from Puching, China. 



EuRYCYPRis SUBGLOBOSA Sowerby. 

 Colombo Lake. Rare. 



Stenocypris malcolmsoni Brady. 

 Colombo Lake. 



Cypricercus reticulatus Daday ? 



A considerable number of specimens of a species of Cyjmcercus 

 were taken in Peradeniya pond. Unfortunately ail appear to be 

 immature, not exceeding '7 mm. in length and with the ovary 

 barely distinguishable. My specimens diflfer somewhat from 

 C. reticulatus in shape and also in the complete absence of any 

 shell-sculpture, but I cannot assign them to any other species 

 nor safely describe them as new. 



Cypridopsis newtoni Brady & Robertson. (PI. III. fig. 16.) 



Syn. C. aldabrce Miiller. 



Great quantities of this species were found in Colombo Lake 

 and a few specimens at MaJuntele. Apstein has recorded Cando- 

 nella alhida Vavra from Colombo Lake, but I have found no
