CRUSTACEA. 
Tauria (Dana, 1853) =! (Kroyer, 1838, preoccupied in Insecta). T. 
medtisarum (0. Fabr.), Bock, 1. c. p. 82, Greenland and Spitsbergen. — T. abys- 
sorum (Bock), id. 1. c. p. 83, pi. 1. fig. 2, Hardangerfjord, Norway, 200-300 
fathoms. 
Parathemisto abyssorum (Bock, 1870), id. 1. c. p. 85, pi. 3. fig. 1, Norway, 
200-300 fathoms.

T. libellula (Mandt)=mc^it*a and crassicornis (Kroyer), id. 1. c. p. 88, pi. 1. 
fig. 5, Spitsbergen. 
TllYPHANIDiE. 
Tryphana malmi (Bock, 1870), Bock, 1. c. p. 92, pi. 1. fig. 3, Hardanger- 
fjord, Norway, 100 fathoms. 
Phronimid^e. 
Phronima sedentaria (Forsk.). The male is distinguished by 
a longer and more stout abdomen and stronger abdominal feet ; 
the shape of the prehensile hand varies according to age. P. 
atlantica (Guerin) is only a younger female of the same species, 
which occurs in all warmer seas of both hemispheres. The little 
gelatinous barrel in which the female dwells is proved to be the 
remains of Pyrosoma. C. Claus, Z. wiss. Zool. xxii. pp, 331- 
338, pis. 26 & 27. 
CVAMID^. 
This group has been reviewed by Alex. Brandt in Bull. 
Petersb. xviii. pp. 113-132 (Mel. Biol. viii. pp. 673-702) ; he 
admits only one genus and the following species : — 
1. Cyamus kesslet'i, sp. n., described and figured (woodcuts), pp. 676-688, 
from a whale in Behring Straits; 2. ovalis (Bouse.), to which may belong 
also the individuals described by the author in M(Sm. Pt5tersb. xvii. p. 26, 
from JBalcena japonica? and those designated C. rhytince?, ibid. p. 20, 
from Kamtschatka; 3. ceti (L., auctt.) = mys^^c^?^^ (Liitk.), from the “right 
whale ; ” 4. monodontis (Liitk.), from Greenland ; 5. erraticus (Rouss.), 
some specimens without known locality ; 6. boopis (Liitk.), from Megapte^-a 
boopHf Greenland; 7. globicipitis (Ijutk.) ? dolphini (Gu^iin, Iconogr.) ; 
8. nodosus (Liitk.), from the narwhal, Greenland, and Delphmus globiceps, 
Faeroes; 9. gracilis (Rouss.); 10. thomsoni (Gosse, Ann. N. H. 1856), 
forming the genua Platycyamus of Liitken. The last two species have some 
resemblance to immature specimens of the others, but nevertheless are 
distinct; the first and second are the most differentiated. Generally the 
females are of smaller size, but relatively, or even absolutely, broader than 
the males ; in the younger state the segments are more equal, and the shape 
of the body is more elongate ; there are no eyes visible when very young. 
Some preliminary notes on the same subject also made at the third meet- 
ing of Russian naturalists at Kiew ; Z. wiss. ZooL xxii. p. 290. 
Cyamus scaminoni, on the Californian grey whale, Rhachianectes glauous 
(Cope) and suffusus, on the “Hump-back,” Megaptera versabilis (Cope), Cali- 
fornia; and C. mysticetif on the northern “Bow-head,” probably Balcena
