Numerous specimens of this species were obtained at various localities 

 both from the Auckland Islands and from Campbell Islands ; it is recorded 

 also from Macquarie Island by Mr. G. M. Thomson. It is known from Kerguelen 

 Island and elsewhere, and is evidently a very common species in subantarctic 



Dns. 



After careful comparison of specimens from various localities, I have no doubt 

 this is the species that has been long known in New Zealand under the name 

 Megamoera fasciculata, G. M. Thomson. Through the kindness of Mr. Thomson I 

 have been able to examine a specimen from Tasmania referred by him to this species, 

 and also to compare it with a specimen from Macquarie Island indentified by him 

 with Atyloides australis, Miers, and I find that these both belong to the one 

 species. 



Mr. Stebbing unites Atylus megalofhthalmus, Haswell, with this species, though 

 embodying in his description some points mentioned by myself in which it differs 

 from the type. My description was taken from specimens collected in Sydney 

 Harbour (the type locality), and I have no doubt that they belong to Atylus mega- 

 lophthalmus, for they agree very closely with the description and the figures that 

 Mr. Haswell gives of the gnathopods and of the uropods. These specimens I have 

 re-examined, and, though they undoubtedly come very close to Paramoera austrina, 

 they appear to differ in the following points : (1.) The head is produced into a rostrum 

 about four-fifths as long as the first joint of the upper antenna. (2.) The appendage
