REPORT ON THE STOMATOPODA. 37 



In its geueral characteristics this species conforms pretty exactly to Mier's description 

 of Squilla duhia of Milne-Edwards {Squilla rubrolineata, Dana and v. Martens), but it 

 may readily be distinguished from this species, which is recorded only from the western 

 shore of the Atlantic, by the absence of sul)median carinas on most of the free somites, 

 and by the alisence of dentations l^etween the submedian spines of the telson.

Diagnosis. — Six teeth on dactylus of raptorial claw. Dentations on inner edge 

 undulating. Eyes directed forward, neai-ly cylindrical, with conical portion hardly 

 wider than the base. Appendages of exposed thoracic limbs strap-shaped. Hind body 

 gradually increasing in width from in front backwards to the fifth abdominal somite, 

 which is equal in breadth to more than one-fourth of the total length. Inner spine of 

 liasal joint of .sixth abdominal appendage longer than outer, with a rounded tooth on its 

 outer and on its inner edge a series of acute dentations gradually increasing in length 

 distally. Rostrum only a little longer than wide. Submedian dorsal caringe entirely 

 absent in all the exposed somites of the hind body except the sixth abdominal. Sub- 

 median spines of telson acute, with about eight intermediate acute dentations. Dorsal 

 surface of telson with four or five sharply defined longitudinal carinse on each side of the 

 median ridge. Paddle of exopodite of sixth abdominal appendage about half as long as 

 second joint, and an acute spine on the dorsal surface of the basal joint of the appendage. 

 Lateral edges of second thoracic somite acute, those of the thiixl and fourth rounded. 



Special Description. — Rostrum only a little longer than wide, subtriangular, with a 

 broadly rounded tip. Antero-lateral angles of carapace acute ; postero-lateral angles 

 rounded ; anterior border nearly transverse ; posterior border deeply notched on middle 

 line. No median carina on the rostrum or on the carapace, the gastric area of which is 

 conspicuously convex. Lateral cariufe of carapace very fointly indicated. No median 

 dorsal tubercle on posterior edge of carapace. Length of rostrum rtlis^ '^^^^^ of the 

 carapace y-^^^'^, and of the two f^^ of the total length. Hind body gradually and 

 uniformly increasing in width from in front backwards to the fifth abdominal somite, 

 which is one and one-half times as broad as the second thoracic somite. There are no 

 submedian dorsal carinjE on any of the exposed somites of the hind body except the 

 sixth abdominal ; the second thoracic somite has no dorsal carina?. The third, fourth, and 

 fifth have each a pair of lateral carina;, and the first five abdominal somites have each 

 three pairs of lateral cariuaj, including the marginal ones ; all of which, except the inner 

 ones^of the first abdominal somite, end in spines. The sixth abdominal somite has well- 

 marked submedian carina; converging posteriorly, and two pairs of lateral ones, all six
