248 BOPYRID^. 



of Pagurus Thompsoni, dredged off Tynemoutli, Aug., 

 1862. 



From Polperro we have received specimens of both 

 sexes, captured by Mr. Loughrin, upon an old specimen 

 of Galathea squamifera, of a much larger size than those 

 represented above, the male being ygths and the female 

 }4ths of an inch long. They precisely agree in general 

 form and in most of their details with the preceding. The 

 feet of the male are, however, more powerfully constructed, 

 with a semicircular emargination on the underside of the 

 hand, but the dorsal appendages of the basal segments 

 of the tail of the female are thicker and more rounded in 

 form, whilst the lateral ones as well as the four attached 

 to the terminal segment are more pointed at their extre- 

 mities and corrugated along their surface. These differ- 

 ences do not appear to us to be incompatible with the 

 enlarged size of the individuals, presuming that those 

 described and figured above are not full grown.
