I 2 1. MR. G. S. BRADY'S MONOGRAPH OF 



C. punctilio ta to the exclusion of almost all other species. It is remarkable that Sars 

 lias found these two species associated in a similar manner on the Norwegian coast. 

 I'rom fossil specimens communicated to me by M. Bosquet, I cannot entertain much 

 doubt that the present species is identical with the C. papillosa of that author, though 

 the recent specimens are uniformly larger than the fossil ones.

Scandinavian type. Distribution : Recent — Baffin's Bay, Norway, Britain. Fossil — Glacial and post- 

 tertiary deposits, England, Scotland, and Norway. 



Carapace of the female, as seen from the side, oblong, subovate or subtriangular, often 



■ 



marked more or less distinctly with a central transverse snlcus ; greatest height equal to 

 more than half the length, situated at the anterior third. Anterior margin broad and 

 well rounded ; posterior narrower, suddenly round or almost angular below, but not so 

 much so as in the preceding species. Superior margin gently arched, highest a little in 

 front of the middle ; ventral nearly straight. Outline, as seen from above, oval, with 

 rather obtuse extremities. End view ovate, narrowed above, broadly rounded below. 

 The shell of the nude is more elongated, and presents differences of proportion much the 

 same as in C. papillosa. Surface rough and quite free from polish, marked with thickly 

 set rounded pittings, in the intervals of which are scattered elevated papillae. Lucid 

 spots six or eight, four in the line of the central sulcus ; the rest in one or two separate 

 patches in advance of the main group. Substance of the shell very dense and thick. 

 Colour dull brown. Superior antenna rather slender, last joint bearing three terminal 

 setae. Distal portion of the first feet more slender than in the preceding species, 

 distinctly three-jointed. Terminal claw of the last pair of feet very long and almost 

 straight, setiform. Distal portion of the right first foot of the male Particulate, the first 

 joint armed in front with a hooked spine, the last joint considerably swollen, its terminal 

 claw short and curved; "right foot of the second pair as in C. papillosa, its terminal 

 segment very small and composed of one joint, the left foot subprehensile, terminal claw 

 bi pectinate. Basal portion of the copulative organs of the male very large, subquadran- 



broader than long; terminal portion short, bearing two processes, of which the 



™> 



anterior is obtuse, the posterior acuminate

Hab. In deep water, 10-60 fathoms. Suffolk coast, dredged by Mr. D. O. Drewett; Loch Fyne [Mr. D. 



Robertson) ; Shetland {Rev. A. M. Norman) ; Hebrides, the Minch {Mr. J. G. Jeffreys). 



Cythericlea punctillata bears much resemblance in general form to C. papillosa. It is, 

 however, a more robust species, higher in proportion to its length, and the postero- 

 ventral angle much less angular. It is also further characterized by a well-marked and 

 sometimes rather coarse surface-sculpture, and frequently by the central transverse 



sulcus, m these latter characters approaching closely 6. torosa ; whilst C. pap 

 possesses, mostly, a smooth, papillose surface, without any trace of pitting and C. torosa
