the spines become. In one specimen the dactyls were almost as long as 

 in S. macilenta, but were much stouter than they are in that species; in 

 this case the spines had almost disappeared. 



Dimensions. — Females varied in length from 59 to 31 mm., and but a 

 single male 27 mm. long was examined. 



Distribution. — New Brunswick; Bay of Fundy, 'Prince' Sta. 5:

The dactyls of the third to fifth pereiopods are long and usually 

 devoid of spines but in many cases one or sometimes two^very small 

 spines were observed near the base of the dactyl. ^n^f |^^1,^ ^

Colour. — Rather large brownish red spots distributed generally over 

 the whole body and its appendages. The background is not so white as 

 it is in S. fahricii, having a more yellowish tinge. Spots more closely 

 packed on the upper half and on the anterior and posterior ends of the 

 cephalothorax than on the rest of it. Also grouped on the dorso-posterior 

 border of the third abdominal segment and on the uropods.
