VARICELLA DENTICULATA SUTURALIS, n. subsp. 



The shell resembles V. d. charmettensis (p. 116) except that 

 the subsutural folds are more emphatic and more numerous, 

 about 4 in one mm. on the last whorl. They are oblique and 

 quite short, and visibly crenulate the upper edge of the whorl, 

 which forms the lower edge of the narrowly channeled suture. 



There are 4 curved linear variceal grooves on the last whorl, 

 not well differentiated from some other shorter grooves. The 

 outer lip is well arched forward, with a slight recess or notch 

 at the lower third, producing an inconspicuous point, which 

 does not, however, project beyond the general outline of the 

 lip, as in other forms of the species, and is not thickened. 

 Length 16, diam. 5, length of aperture 6.7 mm. ; whorls 7. 



Haiti: ruins of the palace Sans Souci, near Milot (C. T. 

 Simpson and J. B. Henderson, Jr.). 



I have figured the soft anatomy of the type specimen on 

 pi. 34, figs. 6, 7, and pi. 39, fig. 24. 



A broken shell from Sans Souci, referred to on p. 117, 

 belongs to this subspecies. 



STREPTOSTYLA SUMICHRASTI Ancey, (p. 151) has been re- 

 described as " Streptostyla siimichrasti Crosse et Fischer 

 MSS. ' ' by Mr. Ph. Dautzenberg, Journ. de Conchyl. Iv, no. 4, 

 p. 327, pi. 6, figs. 2, 3 (March 30, 1908). I have copied 

 one of Dautzenberg 's figures on my pi. 52, fig. 8.

 or no sculpture, and generally it is somewhat transparent.
