Ciiii/rox. — Crustacea of ihc Kerniadec Islands. 567 



Oxycephalus clausi Bovallius. 

 0,11/cephalus clausi Stebbing, Rep. V'oy. " Challenger," 29, p. 1583, pi. 202. 

 1888. 



One specimen cast up on Terrace's Beach, Sunday Island, and two im- 

 perfect specimens washed up on Flat Beach. 



The perfect specimen agrees closely with Stebbing's descriptions and 

 figure. He points out that the species is nearly allied to 0. edivardsii G. M. 

 Thomson, which is occasionally wasiied up on New Zealand shores, but 

 that there arc differences in the gnathopods, the fifth peraeopod, &c. In 

 the Kermadec specimens " the postero-lateral angles of the first three seg- 

 ments [of the pleon are] produced into a short sharp point, behind which, 

 at some distance, the hind margin forms a similar point " as described by 

 Stebbing, while in 0. novae-zealandiae it is only the hind margin that is 

 produced into a point. 



Caprella acutifrons Latreille. 

 Caprclla acutifrons Mayer, Die Caprelliden der Siboga-Expedition, 24, p. 79, 

 pi. 3, figs. 4-28 ; pi. 7, figs. 62-65 ; 1903. 



A large nmnber of specimens of both sexes and of various sizes " from 

 husk of cocoanut washed up on Denham Bay Beach, Sunday Island." 



These specimens show all the essential characters given by Mayer, and 

 must be referred to this widely distributed species. The assignment of 

 them to any one of the numerous varieties described by him is a much more 

 difficult task ; but in the shape of the second gnathopod, with its concave 

 palm, &c., the thickened peduncle of the first antenna, and the lateral ex- 

 pansions of the third and fourth segments of the body they resemble 

 var. porcellio, from the Cape of Good Hope. 



Another variety occurs at Port Jackson, Australia, and the species as a 

 whole is very widely distriljuted, though it has not been recorded from 

 New Zealand. 



Order ISOPODA. 

 Rocinela orientalis Schiodte and Meinert. 

 Bocinela orientalis Schiodte and Meinert, Naturhistorisk Tidsskrift, ser. 3, 

 12, p. 395, pi. 13, figs. 1-2, 1879; Stebbing, Trans. Linn. Soc, 

 Zool., 14, p. 101, 1910; Richai-dson, U.S. Bureau of Fisheries, 

 Document No. 736, 1910. 

 One ovigerous female cast up on Denham Bay Beach, Sunday Island. 

 This specimen agrees very closely indeed with Schiodte and Meinert's 

 description and figures. The whole of the dorsal surface is light brown in 

 colour. 



They record the species from the Philippines and from Calcutta ; the 

 specimen examined by Mr. Stebbing was from Zanzibar. 



Meinertia imbricata (Fabricius). 

 Oniscus imhricatus Fabricius, Mantissa Insectorum, 6, p. 241, 1787. (Jera- 

 tothoa banJcsii Miers, Cat. N.Z. Crust., p. 105, 1876. Meinertia im- 

 bricata Stebbing, South African Crustacea, pt. 1, p. 58, 1900. 

 Several small specimens from Sunday Island (Captain Bollons, 1907) ; 

 others from the throat of a " maomao " (Scorpis aequipinnis) , Sunday Island 

 (W. R. B. Oliver, 1908) ; and one collected by Mr. Roy Bell. 



The species is widely distributed in the Indian Ocean, South Africa, &c.
