with movable tips, no submedian denticles, ten to eleven small 

 intermediate ones, and one lateral one" Each lateral and inter- 

 mediate spine has a small tooth adjacent to its base on the inner 

 side. Between the submedian spines the margin is divided by a 

 deep median sinus into two rounded or somewhat quadrate, 

 usually smooth, lobes- 

 Length, from tip of rostrum to apex of submedian spine of 

 telson, 82.5 mm.

As observed by Miers and others^ the earlier name Coronis,. 

 Latreille, is preoccupied- Bigelow supplies the more important 

 references and the following diagnosis: — 



" Stomatopoda havino- the sixth abdominal segment separated 

 from the telson by a movable joint; the hind body depressed,, 

 loosely articulated and wide; the dactylus of the raptorial claw 

 without a basal enlargement, but with not less than five m,arginal 

 teeth ; no more than four denticles, and often only one, between 

 the intermediate and submedian marginal spines of the telson, 

 which is usually wider than long; and the outer spine of the basal 

 prolongation of the uropod usually longer than the inner one."
