40 MR. E. J. MIERS ON CRUSTACEA FROM [Jan. 14, 



Rhizopid^. 



Typhlocarcinus villosus. 



Tijphlocarcinus villosus, Stimpson, Proc. Ac. Nat. Sci. Phil. p. 96 

 (1858). 



A very small male individual is in the collection, without definite 

 locality, which I refer to this species. The carapace and legs are 

 clothed with a dense, short, whitish pubescence, with longer hairs on 

 the margins, near which the scattered granules, which are elsewhere 

 probably concealed by the hairy coat, are visible. The hands are 

 covered' with minute subseriate acute granules. The antero-lateral 

 marginal teeth are very small, and can only be seen by removing the 

 hairs. Length 2\, breadth 3 lines. 



The specimen agrees with one (a female of larger size) from the 

 Chinese seas, in the British Museum, presented by the Smithsonian 

 Institution.

Leucosia h^matosticta, junior?

Two specimens were collected, in which the beautiful coloration is 

 very well preserved, and wbich differ from the typical specimens in 

 the British-Museum collection and White's figure as follows: — The 

 blood-red spots on the carapace and legs are more numerous and 

 smaller, the tubercles on the arms proportionally smaller but 

 similarly disposed, the postabdomen of the male with the sides nearly 

 straight and the second joint not constricted, whereas in the typical 

 L. hamatosticta the second joint is broad at base and greatly 

 narrowed near the distal extremity (see figure quoted). Length of 

 male 4| lines. 



Lat. 33° 10' N., long. 129° 12' E., at a depth of 36 fathoms. June, 

 1876. One male. A female is in the collection without definite locality. 

 The differences mentioned, although at first sight sufficiently 

 marked, are probably due to the difference in age of the specimens, 

 which agree in the form of the carapace, front, thoracic sinus, and 

 legs. The male individual obtained by Mr. Adams measures rather 

 more than g inch (6g lines). 



PSEUDOPHILYRA, gCU. UOV. 



Allied to and intermediate between Leucosia and Philyra, but 

 differing from the former genus by the absence of the pit or cavity 

 in the subhepatic region which Prof. Bell has called the thoracic 

 sinus, and from Philyra in the prominent tridentate front and 

 slenderer straighter exognath of the outer maxillipeds. 



So far as I am aware, this genus includes only the following species, 

 Pseudophilyra tridentata and Pseudophilyra ^erryi, described by
