or examination of the animals within ; and such identifications are 
dismissed in a very summary manner by Muller in his “ Monographic 
der Ostracoden ” ( F '. and F. d. Golfes v. Neapel, 1894), who deals 
with the Ostracoda by characters drawn from the limbs, precisely 
as with other groups of Crustacea. 
Calanus finmarchieus, Gunner. — This abundant northern form 
is said to have been taken in the surface net in lat. 35° 9' S., long. 
45° 30' E. Also reported by Brady (Chall. Rep., Copepoda, p. 
32), from off Cape Howe, Australia. After calling attention to 
certain apparent differences, Dr Brady says, “ the only reasonable 
course is to consider both the northern and the southern forms as 
belonging to one species, probably the most abundant and most 
widely distributed of all the Copepoda .” The genus, of which 
Giesbrecht enumerates fourteen species ( F . and F. d. Golfes v. 
Neapel, Pelagische Copepoden, p. 89), is cosmopolitan. Calanus 
valgus, Brady, which Giesbrecht assigns to C. minor, Claus, C. 
gracilis, Dana, and C. yropinquus, Brady, are instances of other 
species whose extended distribution ranges north and south of and 
between the tropics. It is C. propinquus that at Kerguelen 
replaces C. finmarchieus in the same abundance as the latter 
occurs in Arctic seas. 
Harpacticus fulvus, Eischer. — Recorded by Brady from pools 
above high-water mark at Kerguelen (Phil. Trans., 168, p. 215). 
This species, which occurs in similar localities in Europe, is also 
stated by Brady to have been got in 35 fathoms off the Yorkshire 
coast (Monogr. Brit. Copepods, vol. ii. p. 151). The latter speci- 
mens had been formerly described as H. crassicornis (B. A. Rep., 
1875, p. 196). 
Scalpellum velutinum , Hoek. — In regard to this species Dr Hoek 
(Chall. Rep., Cirripeds, p. 96) says, “This beautiful species is 
represented by a single specimen (from 1425 fathoms north of 
Tristan d’Acunha). Provisionally there must be referred to the 
same species three smaller specimens which were dredged near the 
southern point of Portugal; yet I am not quite sure that they 
belong really to the same species. This species is nearly related to 
S. regium, S. Darwinii , S. gigas, S. robustum, etc.,” and this group, 
like the genus as a whole, covers an immense range of distribution.
