not only remarkable on account of its very large size (in 

 which it is only exceeded by the gigantic Antarctic species 

 mentioned by Dr. v. Willemoes-Suhm as having been ob- 

 tained by the ' Challenger ' expedition), but also as consti- 

 tuting the type of an apparently new genus allied to, but 

 distinct from, Pasithoe and Rhopaiorhynchus'^ . 



The precise locaHty is, moreover, one hitherto unexplored 

 by the naturalist. 



Dr. Carail Heller, in his account of the Crustacea collected by 

 the late Austrian expedition to the North Pole (Denkschr. der 

 Akad. der Wissensch. Wien, xxxv. p. 25, 1878), enumerates 

 twenty-four species of Crustacea and three of Pycnogonida, 

 most of these, unfortunately, without precise indication of 

 locality; and Mr. W. S. M. D'Urban has recently given an 

 account of the Crustacea with other Invertebrata collected by 

 Mr. W. J. A. Grant in the Barents Sea during two expedi- 

 tions of the Dutch vessel ' Willem Barents,' in 1878 and 



1879. Nineteen Crustacea and five Pycnogonida were ob- 

 tained in these two expeditions. They were determined by 

 the Rev. A. M. Norman and Prof. J. O. Westwood : and all 

 seem to have been collected in latitudes considerably to the 

 south of Franz-Josef Land. (See Ann. & Mag. Nat. Hist. 



1880, vol. vi. p. 262). 



Decapoda. 

 Crangon [Cheraphilus) horeas (Pliipps). 

 An adult male, length 3 inches 3 lines. 



Hippolyte Phippsij Kroyer. 



Four specimens of the female form (described by Kroyer as 

 H. turgida) are in the collection ; length of the largest 1 inch 

 8 lines. There is also a specimen which is probably to be 

 referred to the male form of this species, in which all the dorsal 

 teeth of the rostrum except the three nearest to the apical 

 spine are obsolete. There are three teeth on the lower margin. 

 The second supraocular spine is distinctly developed. Length 

 about 1 inch 5 lines. 



Hippolyte polaris (Sabine). 



Six females are in the collection. The length of the largest 

 is not less than 2 inches 5 lines. The rostrum in this series 

 is l^-toothed. With these specimens is one that is very

 Prof. G. 0. Sars, on the new Crustacea and Pycnogonida collected 

 during the Norwegian Expedition in 1877-78, and published at Chris- 

 tiania during the present year (1880).
