long. 49" 38' E., Irom a ilepth of GT fathoms. Other specimens were obtained on Sept. 6, l^Sl, in lat. TV 7' K., 

 long. 49° 37' E., from a depth of 170 fathoms. An examination of these has shown that the fingers of the gaathopods 

 precisely agree in dentation with those of the specimen described in the Challenger Report under the name of Podocerus 

 hoeki. That specimen was taken iu the neighbourhood of Xew Zealand, July S, 1874, in hit. 4i.>° 2S' S., long. 177' 43' E., 

 and was supposed to come from a depth of 11 W fathoms. But though its habitat is sepiu-atei.1 by so vast a ilistance 

 from the Arctic localities, there does not seem to be a single feature which can be relied on for distinguishing it from 

 the species to which Dr Hokk had earlier given a name. — (Stebbisg, " The Amphipoda collected during the voyages of 

 the Willem Bai-ents iu the Arctic Seiis in the yeai-s 1S8V^-1S84," Bijdrmjen tot de Dierkunde, Atl. 17, 1S94, p. 45.) 



' Two specimens of a deep-sea Isopo<l, belonging apparently to the same species [AeanthomuiiHa prvteas}, are 

 referred to this genus ; they were dredged in 7CK> and 1 100 fathoms respectively off New Zealand. The genus is 

 remarkable for its dense spiny covering, a condition met with in other deep-sea and cold-water Isopoda. The 

 specimens only differ hxim each other in colour ; the lai-gcr specimen (from llOt) fathoms) is of a pale butf colour, the 

 smaller of a rich brown. — (Beddakd, Zool. Ohall. Exp., p;irt 48, pp. 47-S.) 



' Acanthephiim ska appears to be both abundant and widely distributed ; it was taken by the Challenger at 

 eleven Stations, more or less distant from one another, — iu the Atlantic and Pacitic Oceans, as far north as Japan, and 

 as far south as New Zealand. Its bathymetrical range is also great, since it has been taken at a distiuice of from less 

 than half a mile to about three miles from the surface of the ocean. It appears to W very prolific also, since some of 

 the females that were captureil carry a lai-ge number of small eggs. — (Spesce Bate, Zool. Chall. Exp., ydvt 52, p. 743X 

 . 5 This genus [.Imie^its] consists mostly of deep-water species, which swim freely in the sea, and during the cruise 

 of the Challenger were never captured in less than 255 fathoms of water. . . . Ariiteiis armatus w:\s captured at seven 

 different localities at depths ranging from 1400 to 2350 fathoms. . . . Running down the eastern coast of South 

 America, in the month of September 1S73, the Challenger must have jiassed through a great multitude of young 

 animals of this genus, varying iu size from 4 to 14 mm., all of which bore evidence of belonging to allit\i sj>ecies. The 

 specimens correspondetl closely excepting in such features as may be dependent upon age. — (Spesce Bate, Zool. iJhail. 

 Exp., i>art 52, p. 311.)
