Note. — Angustata, Comptoni, declivis, piperita (bicolor}, 

 pulicaria. As these are all probably of one specific origin, 

 their separation becomes little more than a question of con- 

 venience. The distinctions above named are, however, 

 reasonably palpable, and it is not very difficult to sort a 

 number of mixed specimens according to them. The shell 

 generally received as the angustata of Gmelin happens to be 

 the broadest of all, but the name may refer to the outer lip, 

 which is narrow in the whole group, or to the reflected dex- 

 tral margin, which is less spread over the back than in most 

 cowries. Comptoni is distinguished by a peculiar angle and 

 depression under it in the outer lip, a nut-brown and convex 

 base, and concave depressions in the margins. Declivis is 

 a more solid shell, with a peculiar deflexion of the anterior 

 extremity, which slopes from the back, and it is of a light 

 colour, sprinkled over the back. Piperita is coloured in the 

 same manner, but is more cylindrical than the preceding 

 species, with a more convex base. The variety bicolor has 

 three rows of angular flame-like markings ; so has also the 

 singular shell, f. 289, from Miss Saul's collection, which, in 

 other characters, resembles angustata. Pulicaria is quite 

 a cylindrical shell, with depressed back, otherwise resem- 

 bling piperita, excepting that the lower part of the colu- 

 mellar groove is expanded. 



A*. Group 5. South-African species, with wide apertures;
