80 PUPOIDES. 



While I do not question the zoological observations in- 

 volved in this discussion, I may venture to suggest that the 

 nomenclatorial questions require further examination, Bru- 

 guiere and Geoffroy, whom he quotes, dealt with shells from 

 the environs of Paris. It is not at all certain that Draparnaud, 

 far to the south in Montpellier, had the same form. Paris 

 specimens, which I do not possess, are required in order to 

 determine just what the typical P. avenacca is. Also, the 

 long list of synonyms and varieties must be gone through to 

 determine whether there is an earlier name for the species 

 Ehrmann has segregated as Ch. clienta. 



PUPOIDES (Vol. 36, p. 108). 



The genotype, P. nitidulus, was first designated by Kobelt, 

 1880: Illustr. Conchylienbuch, p. 267. 



Add to synonyms: Themapiipa Iredale, The Victorian 

 Naturalist vol. 47, Nov. 1930, p. 120, mt. Pupa heltiana Tate. 



Mr. Iredale states that " it has no real relationship " with 

 Piipoides, but he does not attempt to mention any differential 

 character in the half page treating of "Themapupa" heltiana. 

 Until such characters are indicated, there seems little reason 

 to regard Themapiipa seriously. 



PuPOiDES MARGINATUS (Say). Vol. 26, p. 111. 



A sinistral specimen was found by Dr. Julia Gardner of 

 the U. S. Geol. Survey in Texas, on the Colorado River, li/^ 

 miles below the Travis-Bastrop Co. line. 



PUPOIDES KARACHIENSIS Pcilc. PI. 18, fig. 8. 



The shell is subperforate with six very convex whorls, apex 

 rather flat. Color (evidently faded) whitish buff. Growth 

 lines faint on spire but a little stronger on back of body whorl. 

 Aperture sub-circular, labrum expanded but not reflexed. 

 Parietal denticle weak. Length 4.5 mm. Diameter of pen- 

 ultimate whorl, above aperture, 1.5 mm. Length of my 

 smallest specimen, 4.1 mm. ; diameter, 1.4 mm. The shell 

 somewhat resembles P. hryantwalkeri Pilsbry, but has more 

 convex whorls and more rounded aperture (Peile).
