on its inner margin. It terminates in two larger teeth, the outer about twice the length 

 of the inner. 



Pseudosquilla dofleini is allied to P. cerisii, and P. lessoni, but is readily distinguished 

 from them by the numerous teeth on the inner margin of the uropodal process. 



The above account is derived from Balss' figure and description of the only known 

 specimen. This example a female, 85 mm. in length, was found in Sagami Bay, Misaki, 

 Japan.

The principal features of this well-marked species are as follows : — 



The rostrum terminates in a prominent acute spine reaching a little beyond the 

 eyes ; its basal portion is about twice as broad as long with slightly obtuse antero- 

 lateral angles. The eyes are short and the cornea is dilated and conspicuously bilobed. 



The dactylus of the raptorial claw possesses four teeth including the terminal one, 

 differing in this respect from all other species of the genus ; its external margin bears 

 a sharply rounded lobe at the proximal end. 



The lateral margins of the sixth and seventh thoracic somites are rounded, 

 broadly in front and narrowly behind. The postero-lateral angles of the fourth 

 and fifth somites are spinous. The fifth bears on either side a deep longitudinal 

 sulcus and a carina close to the margin. The sixth somite bears six smooth triangular 

 elevations ending in sharp spines and between the submedians and intermediates, 

 there is a small rounded tubercle. 



The telson is twice as broad as long and, as in P. dofleini, bears the full number 

 of carinae. The median terminates in a sharp spine; the submedian consists of 

 a carina in the anterior half ending in a spine and succeeded by one, more commonly 

 by two, spines; the intermediate is entire and ends in a spine overhanging a small 

 tubercle before reaching the margin behind the outer intermediate denticle; the first 

 lateral may be interrupted and terminates in a spine overhanging a tubercle at 

 the base of the intermediate marginal tooth. The second lateral is continued to the 

 apex of the lateral marginal tooth. Between the two laterals there is, in the single 

 specimen examined, an additional short carina ending in a spine. On the margin the 

 usual three pairs of primary teeth are prominent, the submedians being mobile. 

 There are two rounded intermediate denticles and one lateral. The inferior surface 

 is smooth except for a pair of spines on either side placed opposite the interspaces 

 of the primary marginal teeth. 



The basal process of the uropods consists of a long and sharp spine, bearing 

 a small spine on its outer margin and a series of five to seven similar spines on 

 its inner margin. 



In colour the single example is pale with dark pigmentation along the sides of the 

 carapace and abdomen.
