APPENDIX. 



ClILAMYDEPHORUS GlBBONST, W. G. Bhiney, p. 17. 



Heynemann has examined a second specimen, in alcohol, from 

 Cape Colony, preserved in the British Museum. He states that 

 the description of a mantle covering the entire body is erroneous, 

 as there is properly no mantle. The original generic name is 

 accordingly inappropriate, and is changed by him to Apera, 

 Heynemann. Jahrb. Mai. Gesell., xii, 17, t. 2, f. 5-7. 



OLEACINA (VARICELLA) LEUCOZONIAS, Walch, p. 26. 

 Does not occur at Martinique, but Jamaica. 



STREPTOSTYLA CATENATA, Pfeiffer. PI. 11, fig. 81. 



Somewhat solid, shining, irregularly striulate; yellowish horny, 

 with a chestnut sutural band, and an interrupted one on the 



middle of the body-whorl. Length, 11 mill.

 STREPTAXTS SUBORBICULA, Dohrn. PI. 13, figs. 35-37.

This section and species are referred (probably correctly), to 

 Buliminus by von Martens (Conch. Mittheil., 144).

Sinuously rimate, somewhat solid, obliquely costulate, suture
