Professor Smith gives a full description of Cerajms tuhuJaris, Say, which he partially figures. 

 It is, he thinks, " not congeneric with any descrihed species, and the genus cannot properly 

 he placed in any of the numerous subfamilies defined by Boeck, though it is probably most 

 nearly allied to his Podocerinse." He proposes for it a new subfamily, Cerapinse, thus 

 described : — 



" The single known genus differs from the Podooerinre and allied groups in the following 

 characters. There are only three pairs of branchial lamell;e, which are borne on the third, 

 fourth and fifth segments of the perreon, and only three pairs of ovigerous lamella, which 

 are borne on the second, third and fourth segments. The second and third pleopods are 

 much smaller than the first, and their inner lamella are rudimentary or very small. The 

 second and third uroijods are uniramus and nearly alike, the distal segment in each being 

 short and terminating in a hooked point. 



" The only known species inhabits unattached, portable tubes, and, as in many allied genera, 

 has large cement glands in the bases of the first and second perteopods." 



Professor Smith at this date regards Cerapus tubularis as the only species, without, however, 

 taking Cerapus aiditus, Templeton, into account. For other species that had been 

 referred to Cerapus, he adopts Eridlionius, M.-Edw. 



Unciola irrorata, Say, is stated to have precedence over GJauconome leucopis, Kroyer. Lepi- 

 dadylis, Say, is preferred to the other names which compete for the designation of Slabber's 

 Oniscus arenarius.
