Chilton. — Crustacea from the Chatham Islands. 271 



Moera fasciculata, G. M. Thomson. Index Faunae N.Z., p. 260. 

 Numerous specimens from Te Whakuru (Miss Shand), some 

 of them rather larger than those usually taken on the east coast 

 of the South Island, where the species is common. I do not feel 

 sure of the generic position of this species ; the secondary 

 flagellum of the upper antenna consists of a single small joint, 

 and the species does not exhibit marked sexual differences, and 

 is very different from other species of Moera that I am acquainted 

 with. I am of the opinion that it comes near to Atyloides, 

 Stebbing. 



Melita tenuicornis, Dana. Index Faunae N.Z.. p. 260. 



One specimen collected by Dr. Dendy. 



This species is common in New Zealand, and is found both in 

 rock-pools on the open sea-coast and also in estuaries and 

 lagoons when the water may be almost or quite fresh. 



Mr. A. 0. Walker has recently recorded it from Ceylon under 

 the name Mara tenuicornis, though pointing out that there are 

 various discrepancies between his species and Dana's descrip- 

 tion and figures of the New Zealand form.* In the same year 

 Mr. Stebbing described from Ceylon a new species, Melita zey- 

 lanica, which he was unable to refer to Dana's species, and dis- 

 tinguishes from it by numerous characters, though he appears 

 to think that these differences may possibly be due to errors 

 and inconsistencies in Dana's descriptions and figures. f 



Phronima novae-zealandiae, Powell. Index Faunae N.Z., p. 256. 



Two specimens in the " casks " washed upon Te Whakuru 

 Beach (Miss Shand), one with numerous young with her in the 

 " cask." 



ISOPODA. 



Exosphaeroma gigas, Leach. Index Faunae N.Z., p. 263. 



Several specimens of this widely spread species were in Mr. 

 Thomson's collection, having been collected by Professor H. B. 

 Kirk. Some of them were larger than those usually found on 

 the east coast of the South Island, being intermediate between 

 these and the large specimens found at the Auckland Islands. 

 On the Chatham Islands specimens were found Iais pubescens, 

 Dana, which appears to be almost invariably associated with 

 this species. 



Mr. Stebbing has fully described Exosphceroma gigas from 

 Falkland Island specimens, and has established for it the genus 



* Am-phipoda, from " Report on the Pearl Oyster Fisheries," 1904, 

 p. 273.
