62 ZOOLOGICAL COLLECTIONS MADE DURING [Jan. 4, 



of Antarctic South America bear a great resemblance to those of the 

 Arctic Seas, and are in many cases congeneric with them, with a 

 few somewhat doubtful exceptions the same species do not occur in 

 the Northern and Southern seas'. 



^ See, however, Lilljeborg, Nova Acta Soc. Upsaliensis, ser. 3, vi. (1866), 

 " Ou the Lysianassa magcllanica, M. -Edwards, &c." I may add that Mr. T. W. 

 Kirk, Transactions New-Zealand Institute, xi. pp. ,"02-401 (1878), has recently 

 identified several Decapoda and Edriophthalmia occurring in the New-Zealand 

 seas with well-known North-European species ; but his identifications seem to 

 me to require confirmation, as it is not stated whether they have been made 

 after comparison with Euroi^ean examples or from the descriptions of authors 

 only. Yet more recently, Mr. G. M. Thomson (Ann. & Mag. Nat. Hist. vi. p. 4, 

 1880) has described a variety of the Arctic Eusirus cuspidatus (which does not 

 differ sufliciently to be distinguished specifically) from Dunedin Harbour, New 

 Zealand. 



Besides the Crustacea obtained on the South-American coasts, the following 

 species were dredged by Dr. Coppinger in the North Atlantic. Amongst them is 

 one apparently new to science, belonging to the very interesting genus Glau- 

 cothoe of Milne-Edwards, a genus previously um-epresented in the British- 

 Museum collection, and which, although Macruran in its organization, and 

 placed by Mihie-Edwards and Dana in the Thalassinidea, presents many afiinities 

 with the Paguridea, and is alhed to the genus Pomatocheles described by me 

 (P. Z. S. 1879, p. 49, pi. iii. iig. 2). 



Herbstia ovata. 



Micropisa ovata, Stimpson, Pr. Ac. Nat. Sci. Phil. p. 217 (1857) ; A. M.- 

 Edwards, N. A. Mus. H. N. iv. p. 51, pi. x^-i. figs. 1, 2 (1868). 



Two males and a female of this pretty little species were collected at St. 

 Vincent (Cape-Verds) on a sandy bottom. When received, although they had 

 been for some time in spirit, they were of a bright rose-colour. 



GLAucoTiioii ROSTEATA, sp. u. (Plate VII. figs. 1-5). 



Carapace as in the Paguridaj, with the cervical and other sutures distinctly 

 marked, inflated over the branchial regions, and with a median, triangular, sub- 

 acute rostriform process ; posteriorly the carapace is much broader than the 

 first postabdominal segment. The postabdomiual segments ai-e smooth ; the 

 second to fifth narrowed on the sides, and these segments are each furnished 

 with a ])air of simple articulated appendages ; the ventral surface of the post- 

 abdomen is closed by a soft and membranaceous skin, as in the Paguridre. The 

 terminal segment is twice as long as broad, suboblong, rounded and fringed 

 with long plumose hairs at its distal end. The eyes are subcylindrical ; thean- 

 tennules aj-e short, geniculated ; and the flagellum is fringed with long hairs on 

 ,its under surface. The basal scale of the antennre is obsolete. The outer 

 maxilli)3edes are short and subpediform. The anterior legs are equal, and ter- 

 minate in perfectly formed but rather slender chelas, the ]3alms of which are 

 compressed, the fingers acute at their apices, and slightly denticulated on their 

 inner margins ; the second and third legs are slender, and reach considerably 

 beyond the first legs, their terminal joints being styliform and nearly straight; 

 the fourth and fifth legs are shaped as in the Paguridse, ; the jjenultimate joint 

 of the fourth legs is somewhat dilated and compressed, and armed with a series 

 of acute serrately disposed teeth on its inferior margin ; the dactylus is strong, 

 arcuate, and acute. The fifth legs are very slender, and the perfectly-formed 

 didactyle chelae with which they are terminated very small ; the fingers are un- 

 armed, and fringed on their outer surface with fine hairs. The terminal joint 

 of the second to fifth postabdominal appendages is fringed with long, flexible 

 plumose hairs. The rami of the nropoda are similarly ciliated, and unequal in 

 size, the inner and smaller being regularly oval, the outer suboblong and 

 obliquely truncated at its distal end. Length ^ inch.
