 204, fig. in text. 



Two of the three cotypes in coll. Hartman ( Carnegie Mus- 

 eum no. 4238) are fignred. I fail to get Hartman 's meaning 

 in calling the shell "flexuose. " It is very closely related to 

 the following species. Fig. 13 shows a portion of the last 

 whorl a short distance behind the aperture. 



82. P. HASTULA Hartman. PI. 35, figs. 6, 7, 8. 



Shell similar to P. flexuosa, ovate-fusiform, thin, covered 

 with a thin cuticle, pale yellow on the last whorl, grayish- 

 corneous on the spire ; rather openly but deeply umbilicate ; 

 sculptured throughout with impressed spiral lines. Whorls 

 moderately convex, parted by impressed sutures which are 

 usually margined above more or less distinctly. Last whorl 

 is laterally flattened and saccate at the base. Aperture longer 

 than in P. flexuosa; outer lip thin, reflexed, thickened with- 

 in except near the posterior termination. 



Length 19.7, diarn. 9.8, aperture 10.7 x 6.7 mm.; whorls 5. 



Length 20, diam. 9.25, aperture 10 x 6.7 mm. ; whorls

 33, pi. 2, f. 9. SMITH, Ann. Carnegie Mus. i, p. 453, no. 4239. 



This form stands extremely close to P. flexuosa, but it has 

 a longer aperture and somewhat thinner shell. The umbilicus 

 is also a little more open in hastula. I hardly think the two 

 specifically distinct. Figures and description from the co- 

 types, no. 4239 Carnegie Mus. 



Dr. Hartman at first gave the locality as "Erromango 

 Island, Solomon Is.," an error for Eromanga, New Hebrides; 

 but on the back of the label he has written "Simbo, Eddy- 

 stone Isl."
