4. Coxus AMMiRALis, Liii. During two years collecting in the 



Viti group we found only a single very perfect live example 

 of this beautiful species, in sandy-mud in the upper region 

 of the laminarian zone. Several small beach worn speci- 

 mens were found in various parts of the group. 



5. CoNUS ARENATUS, Brug. Commoii at the Viti Islands, less 



so at the other groups, and very rare at the Cook's Islands; 

 the limits of its range in Eastern Polynesia. Most generally 

 found buried in coarse sand. 



6. Coxus AULicus, Lin. Very rare; no living examples found. 



7. Coxus AURATUS, Brug. This is also a very rare species; found 



lurking under stones at low water mark. 



8. Coxus AUREUS, Brug. Very rare; only found in the condi- 



tion of dead shells. 



9. Coxus BULLATUS, Lin. Only several dead but very perfect 



examples found on reefs. 



10. Coxus BALTEATUS, Sow. Not common; found among sea- 



weed near low water mark. 



11. Coxus COELEBS, Hds. We obtained a number of examples 



of this species in the upper region of the laminarian zone, 

 on sandy-mud bottom at the Island of Vanua Levu, Viti 

 Islands. 



12. Coxus CAXoxicus, Brug. A rare species ; found hiding under 



stones on reefs. The animal is flesh-white with a buff- 

 yellow creeping disk, which, together with the upper surface 

 of the foot is delicately marbled with rich reddish-brown, 

 and the ends of the same organ edged or tinged with 

 rose-red. The siphon and tentacles are white, the former 

 tipped with rose-red and ornamented with an anterior 

 transverse black spot
