LEPTOSTRACA, SCHIZOPODA AND STOMATOPODA. 167 



Distribution : S. nepa has already been recorded from Ceylon by HELLER (1868). 

 Its distribution is general over the whole of the Pacific and Indian Oceans. 



Pseudosquilla ciliata (FABRICIUS), MIERS. 



Locality : Talaivillu Paar, off south end of Mutwal Island, 10 to 14 fathoms. 

 One male, 33 millims. 



It is interesting to note that this specimen agrees with BROOKS' West Indian 

 examples in those points in which the latter differ from the Pacific ones. I have 

 confirmed this by an examination of BROOKS' " Challenger" specimens. BORRADAILE 

 (1900) has proposed the varietal name occidentals for this form. 



Distribution : P. ciliata has been recorded from Ceylon once previously by 



F. MULLER (1887). It is another widely distributed Indo-Pacific form. 



% 



Gonodactylus chiragra (FABR.), var. smithii, POCOCK (1893). 



Locality : Muttuvaratu Paar, 45 to 50 fathoms, in cavities of coral. One female, 

 12 millims. 



This specimen agrees very well with LANCHESTER'S var. smithii (A) (LANCHJESTER, 

 1902), except that the spine on the median carina is perhaps not so well developed. 



Distribution: China seas (PococK, 1893); Funafuti and the Loyalty Islands 

 (BORRADAILE, 1898) ; Malay Peninsula and the Maldives (LANCHESTER, 1902). 



Gonodactylus chiragra (FABR.), var incipiens, LANCHESTER (1902). 



Locality : Trincomalee. One male, 18 millims. 



The single specimen which I refer to this variety of the type species agrees with 

 LANCHESTER'S var. incipiens (A) (1902, plate xxiii., fig. 10). 

 Distribution : Funafuti (LANCHESTER). 



Gonodactylus glabrous, BROOKS (1885). 



Localities : 



Cheval Paar, 6 to 8 fathoms. One female, 46 millims. ; one male, 16 millims. 



Coral Keefs, Gulf of Manaar. Three females, 40, 30 and 15 millims. ; one male, 

 34 millims.
