stitutes the palm. The perseopods are very similar to those 

 usual in the genus ; the front margin of the propodos in the 

 earlier limbs lias usually four clusters of spines, that of the 

 last pair with five clusters. The last uropods (fig. 7) have 

 their branches not only spined as usual, but their meeting 

 margins and both sides of the terminal points are microsco- 

 pically serrulated. The telson (fig. <S) is of the usual simple 

 elongate-triangular form, perhaps rather longer in proportion 

 to its breadth than in allies. Length 4 to 4'5 mm. 



This species, which had been put aside for description, 

 was seen, on the receipt of Prof. Sars's account of Apherusa 

 Clevei *, to be very near to it in character. We therefore 

 thought it well to send specimens to him for his comparison 

 and opinion ; his judgment on it was, " It is a very distinct 

 species/' It appears to us to be, as it were, an exaggerated 

 form of A. Clevei, from which it chiefly differs in the much 

 greater development of the dorsal spines of the first two 

 segments of the metasome. and the character of the hinder 

 margin of its third segment.
