Show 1879.] THE COREAN AND JAPANESE SEAS. 51 cothoe of Milne-Edwards1. The latter, which is placed by Dana in the Gebiidee, is only known to me by the figures and descriptions of its author; it presents decided affinities with the Paguridea in the form of the fourth and fifth legs of the cephalothorax, eyes, antennae, and anterior legs, which are more distinctly Macruran in type. Glaucotho'e has been considered by Mr. Spence Bate2 to be but the immature condition of Pagurus; and he figures and notices a specimen of that or a closely-allied genus that had been taken floating on the surface of the sea. Whether his contention be correct or not (and his remarks and figures do not appear to me to suffice to decide the question), there can, I think, be little doubt that the specimens of Pomatocheles I have examined are mature ; and the fact that they had been found at considerable depths permanently ensconced within the shell of Dentalium seems confirmatory of that opinion. From Glaucotho'e Pomatocheles is easily distinguished by the form of the chelae of the anterior legs and of the carapace, not to mention other characters. GALATHEIDEA.1 GALATHEA ORIENTALIS. Galathea orientalis, Stimpson, Proc. Ac. Nat. Sci. Phil. p. 252 (1858). A large series of this species was collected, the specimens agreeing in all respects with Stimpson's description, and the number of spines on the gastric region and lateral margins being remarkably constant; only it is to be noted that the large spine on the inner surface of the wrist varies considerably in size, sometimes not being much larger than the other spinules of the anterior legs; there is usually a small tooth on the inner margin of the immobile finger. This species, like the Pilumnus hirsutus and Cymodocea trilobatat to be described in the second part of this Beport, is a very common inhabitant of the Chinese seas, having been dredged at no fewer than nine different localities in or near the Corean Straits, at depths varying from 12 to 50 fathoms. Stimpson's specimens were from the Ly-i-moon Straits, near Hong-Kong. MUNIDA JAPONICA. Munida japonica, Stimpson, Proc. Ac. Nat. Sci. Phil. p. 252 (1858). A single specimen was collected in the Corean Straits, lat. 33° 14' N., long. 182° 55' E., at a depth of 40 fathoms. The legs are, unfortunately, wanting ; but in the form of the carapace and rostrum, and the number and position of the spines of the cephalothorax, it agrees perfectly with Stimpson's description, whose specimens were collected at Kagosima, Japan. 1 Ann.
