margin longer than the inner; a raptorial claw with four teeth on the 

 dactylus and two dorsal teeth on the carpus; a relatively broad, 

 flattened body, with the abdomen partially carinate; a telson broader 

 than long, with submarginal intermediate and lateral denticles; 

 and a basal prolongation of the uropod with the inner spine the longer, 

 armed with spinules on its inner margin. The single species of 

 Coronidopsis, C. biscuspis Hansen, differs from the three species now 

 recognized in Manningia in having an anteriorly bifurcate rostral 

 plate and numerous dorsal spinules on the telson. 



The terminology of the carinae of the telson proposed by Kemp 

 (1913, p. 13, text-fig. 4) and currently used in this and related genera 

 is illogical in that dorsal carinae may bear names different from the 

 marginal teeth on which they occur. Thus, as used by Kemp, the 

 intermediate dorsal carina extends onto the submedian marginal 

 tooth and the first lateral carina extends onto the intermediate 

 marginal tooth. In the carinal nomenclature used herein by me, 

 the name of a dorsal carina is derived from that of the marginal 

 tooth onto which it extends. The proposed nomenclature of the 

 carinae of the telson in Manningia and related genera compared with 

 that proposed by Kemp (1913) is as follows:
