long. 49° 38' E., from a depth of 67 fathoms. Other specimens were obtained on Sept. 6, 1881, in lat. 77° 7' N., 

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

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

 hoelti. That specimen was taken in the neighbourhood of New Zealand, July 8, 1874, in lat. 40° 28' S., long. 177° 43' E., 

 and was supposed to come from a depth of 1100 fathoms. But though its habitat is separated by so vast a distance 

 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 Hoek had earlier given a name. — (Stebbing, " The Amphipoda collected during the voyages of 

 the Willem Barents in the Arctic Seas in the years 1880-1884," Bijdragen tot de Dierkunde, An. 17, 1894, p. 45.) 



1 Two specimens of a deep-sea Isopod, belonging apparently to the same species [Aeanthomunna proteus], are 

 referred to this genus ; they were dredged in 700 and 1100 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 from each other in colour ; the larger specimen (from 1100 fathoms) is of a pale butt' colour, the 

 smaller of a rich brown. — (Beddard, Zool. Ghall. Exp., part 48, pp. 47-8.) 



2 Acanthephyra sica appears to be both abundant and widely distributed ; it was taken by the Challenger at 

 eleven Stations, more or less distant from one another, — in the Atlantic and Pacific 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 distance of from less 

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

 the females that were captured carry a large number of small eggs. — (Spence Bate, Zool. Ghall. Exp., part 52, p. 743). 



3 This genus [Aristeus'] consists mostly of deep-water species, which swim freelj' in the sea, and during the cruise 

 of the Challenger were never captured in less than 255 fathoms of water. . . . Aristeus armatus was 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 1873, the Challenger must have passed through a great multitude of. young 

 animals of this genus, varying in size from 4 to 14 mm., all of which bore evidence of belonging to allied species. The 

 specimens corresponded closely excepting in such features as may be dependent upon age. — (Spence Bate, Zool. Ghall. 

 Exp., part 52, p. 311.)
