16 The Pleistocene Deposits of Sankoty 



PANOMYA NORVEGICA Spengl. (Saxicava norvegica, Verrill, 1875, 

 p. 373). 



A single valve of this species is recorded by Verrill from the 

 upper shell bed. It is very probable that the fragments recorded 

 by Hollick as Panopaea sp? may be referable to this species. 



MOLLUCSA GASTROPODA. 



PUNCTURELLA NOACHiNA Linn. (Diodord noachina, Verrill, 

 1875, p 373). 



Verrill records "two good specimens" of this from the upper 

 shell bed, No. 3. 



SOLARIELLA OBSCURA Couth. (Margarita obscura, Merrill, 1896, 

 p. 13). 



Fragments of this shell were found by Merrill in bed 4. 



SKENEA PLANORBIS F. and H. (Merrill, 1896, p. 13). 

 This species was found by Merrill in bed 4. 



*ODOSTOMIA IMPRESSA Say. (Verrill, 1875, p. 371). 

 This small shell is common in the lower shell bed, No. 1. 



*ODOSTOMIA SEMINUDA C. B. Adams. (Cushman, 1905, p. 195). 

 Specimens of this species were found during the last summer in 

 loose material evidently from bed No. 1. 



*ODOSTOMIA TRIFIDA Gould. (Verrill, 1875, p. 370). 

 Fairly common in the lower shell bed, but apparently less 

 common than O. impressa Say. It is also found in bed No. 1. 



*ODOSTOMIA BISUTURALIS Say. (Cushman, 1905, p. 195). 

 Found during the last summer with O. seminuda C. B. Adams. 



*ODOSTOMIA FUSCA C. B. Adams. (Cushman, 1905, p. 195). 

 A single specimen, apparently referable to this species was 

 found in the loose material. 



TURBONILLA INTERRUPTA Totten. (Verrill, 1875, p. 371). 

 Found sparingly in beds 1 and 2. 



SCALA GROENLANDICA Perry. (Desor and Cabot, 1849, p. 342). 

 Very rare, apparently found in bed No. 3, as it is a northern 

 species.
