Type B.M. no. 98. 5. 15. 4. 



This handsome species may be readily distinguished from 

 M. cinerea, its nearest ally, by its dark yellowish belly, 

 uniformly brown tail, and the narrowness of its nasals and 

 interorbital region. 



MISCELLANEOUS. 



Malaeostraca from Puget Sound, N.W. America. 

 By Alfred 0. Walker. 



On the occasion of the visit of the British Association to Toronto 

 in 1897 Prof. W. A. Herdrnan, F.E.S., made a trip to the Pacific 

 coast, and had two or three days' dredging off Port Townsend in 

 Puget Sound and Victoria, B.C. Among other marine animals 

 taken were 33 species of Malaeostraca, of which 7 appear to be new 

 to science and 4 are European species, of which I can find no record 

 from the west coast of North America. These last are all Amphipoda, 

 viz. Leucothoe spinicarpa (Abild.), Melita dentata (Kroyer), Ischyro- 

 cerus minutus, Lillj., and Podoceropsis excavata (Sp. Bate). 



Trichocarcinus (Platycarcinus) recurvidens (Sp. Bate, Ann. & Mag. 

 Nat. Hist. ser. 3, vol. xv. p. 488) is redescribed, and the family 

 Trichoceridae, De Haan, abolished, the genus Trichocarcinus being 

 placed next to Cancer, from which it differs in the greater promi- 

 nence of the regions of the carapace. 



The new species, which, like the last, are fully described and 

 figured in the Trans. Liverpool Biological Society, vol. xii. pp. 268- 

 287, pis. xv. and xvi., are as follows : — 



Crangon miaiitellus. 



Near C. munitus, Dana, but differing in its much smaller size and 

 in the second thoracic carina from the median terminating in a 

 tooth halfway to the orbital margin, while in C. munitus it reaches 

 the margin and has no tooth.
