is shorter and just reaches insertion of 2nd internal seta on 3rd 

 exopodal segment (same condition is in Tanaka's specimen of 0. 

 oculata) . 



3. Apical spine on 3rd exopodal segment of leg 4 long in 0. oculata, 

 slightly longer even than whole exopodite. In 0. alia it is much 

 shorter and reaches the length of the two apical exopodal segments 

 combined. 



The variability of the featm-es 2 and 3 is unknown and 0. alia might 

 well prove to be the Atlantic form of 0. oculata, the visibility of the 

 gangliac mass being dependent upon the condition of fixation. 



0. oculata is distributed rather irregularly over the tropical and 

 subtropical parts of the Indian and Pacific Oceans: it has been recorded 

 from Samoa in the Pacific Ocean (Rosendorn, 1917); from Christmas 

 Island in the Indian Ocean (Farran, 1913a); from the coastal waters 

 off New South Wales, Australia (Dakm and Colefax, 1933, 1940); 

 from Nancowry Harbour in the Nicobar Islands (Sewell, 1947, 

 1 ad. cf ) ; and from south of the Cape of Good Hope (Tanaka, 1960). 



Family Cyclopinidae G. O. Bars, 1913 



This family, in its present form, comprises a fairly large number of 

 closely related genera, distinguished by such characters as the segmen- 

 tation and setation of leg 5, setation of legs 1 to 4, and the development 

 or oral appendages and antennules. 



The various genera have been revised by Lindberg (1953) and 

 may, with the genera and species added since, be given as follows:
