PLATE VII 



Figure 1. Bulimus tristis, Nobis. 



Habitat, Zanzibar. 



Remarks. — This shell is entirely new in our collections, and was received by 

 Mrs. S. Dunlap, of Salem, Mass. who very kindly sent me the specimen which I 

 have figured. The color is the same both externally and internally ; the lip is 

 acute ; is slightly unibilicated, and has numerous longitudinal stria^ 



Figure 2, 3. Conus rhododendron, Conthuoy. 



" C. testa cylindracea tuibinata, rcjsea, alba et fasca nubilala, punctis cinnamomeis superne infer- 

 neque notata, striis transversis sulciformibus numerosis, spira obtusa, columella superne sulcata, 

 fauce alba."

Habitat, Seas of Australasia. 



" Shell cylindrically turbinate, of a blush rose color, longitudinally clouded 

 with white and pink, surrounded by three bands, composed of irregularly 

 grouped triangular pinkish colored dots ; the first near the spire, the two lowest 

 near the base, the interval being without spots : circled by about 30 impressed 

 transverse striae, which, near the base, deepen and widen into distinct sulcations ; 

 are inconspicuous near the middle, and become more prominent again near the 

 spire. The spaces between these striae are flattened in such a manner as to give 

 the shell the appearance of being ribbed or hooped ; thickly set, minute longi- 

 tudinal striations cover the whole surface, but are most apparent in the trans- 

 verse sulci — spine obtuse — its whorls concave, with three or four revolving 

 striae on each ; aperture dilated at the base, with a strong oblique sulcus at the 

 superior portion of the columella, and a prominent ridge near its lower extre. 

 mity — lip internally of a rich cream color." 



Remarks. — This very beautiful shell, which in the richness and delicacy 

 of its coloration is equalled by few of the Genus, was presented to me by Augus- 

 tus A. Adee, Surgeon U. S. N. It measures exactly two inches in length.
