304 COLLECTIONS FROM MELANESIA. 



of Wales Channel (7-9 fms.). The antennae are imperfect. Two 

 specimens, of unknown locality, are in the British Museum from the 

 collection of H.M.S. ' Herald.' 



The mandible, in its broad and strongly dentated apex, closely re- 

 sembles that of C. srhliii/tei. 



Cirolana latistylis, Dana, from the Balabac Straits, is very imper- 

 fectly described, but appears to be distinguished from this species by 

 the much broader inner ramus of the uropoda. 



(>. Cirolana lata, Haswell, var. integra. 



Three small specimens from Albany Island, 3-4 fms., are referred 

 with much hesitation to this species. In the broadly ovoid form of 

 the body, with its longer first thoracic segment and short post- 

 abdomen, they resemble Mr. Haswell's figure and description* ; but 

 the terminal postabdominal segment is less acute than in the figure, 

 and thero is no tooth upon the inner edge of the inner ramus of the 

 uropoda. I may add, in reference to some points that are not 

 mentioned in Mr. Haswell's description, that the eyes are black and 

 subquadrate, the median rostral point prominent and prolonged 

 between the bases of the antennules to or nearly to the apex of 

 the interantennal plate, which is nearly of the same form as in 

 C. sckibdtei, but is without a superficial tooth ; the apex of the 

 mandible is broad and dentated as in other species of the genus ; the 

 basal joint of the antennules is large and considerably dilated ; the 

 fiagellum of the antenna? (which is short and scarcely reaches beyond 

 the posterior margin of the first body-segment, as in Haswell's figure) 

 is 13-15-jointed. 



7. Rocinela orientalis, Schibdte 4' Meinert. 



A single female is referred here in Dr. Coppinger's collection from 

 Prince of AY ales Channel, 7-9 fms., which has lost the inner ramus 

 of both uropoda. 



Specimens are in the British-Museum collection from Moreton 

 Bay. 



If a male and female from Ceylon (E. W..H. Holdsworth) and 

 a male from the Gulf of Suez are correctly regarded as identical 

 with this species (and they do not seem to differ markedly from the 

 Australian examples), this must be a widely distributed Oriental 

 form. A large specimen from the West-African coast (without 

 special indication of locality) comes very near to this species, but 

 has a more acute and prolonged front and posterior epimera, and 

 differs slightly in the proportionate length of the joints of the 

 antenna' and antennules, and may be distinct. Messrs. Schiudto 

 and Meinert's types were from the Philippines and Calcutta. 



Mr. Haswell has described a species, Rocinela vigilans, from 

 Holborn Island, near Port Denison [vide Cat. p. 285), which seems 



* Proo. Linn. 8oe. N. S. Wales, vi. p. 102, pi. iv. fig. 1 (1881); Cat. p. 286
