STELFOX: GASSIES COLLECTION OF PISIDIA. 57 



Langoiran is situated on a small tributary of the Garonne, 

 and these four examples are evidently river-shells. 



Card No. 135. "P. ohtusale. Cyclas. Lk. 

 Libourne — Paillet — le Teich." 

 7 perfect shells. 



What the P. ohtusale of Lamarck really was is unknown, but 

 none of the seven shells is referable to the P. ohtusale of 

 Jenyns and more recent authors. The first shell on the 

 card is a thickened elongate, rather quadrate, P. casertanum. 

 The remaining six shells are all P. personatum, but larger, 

 and rounder, than one normally finds it. On the back of the 

 card is scribbled in pencil " pusillum ", and over this in ink 

 " Pusillum, Jennyns " [sic] ; a perfectly correct determination 

 aa Jenyns' spusilhtmixiciuded both personatum and casertanum. 



Card No. 136. " P. Gassiesianum, Dup. 

 Begles — Blanquefort — le Taillan. 

 All shells broken. 



Card No. 137. " P. nitidum, Jennyns [sic]. 

 Begles — la Tresne — Coutras." 

 All shells broken. 



Card No. 138. " P. pusillum. Tellina, Gml. 

 Les fontaines, les Esteys, les Euiss [-eaux]." 

 9 perfect shells ; also 1 broken. 



Of the nine perfect shells 8 are P. suhtruncatum. Malm, and 

 one, the largest (eighth from the left) on the card is 

 P. casertanum. The broken shell (the tenth on card) cannot 

 be named. On the back of the card is scribbled in pencil 

 " fontinalis ", and over this in ink is written " fontinalis, Pfr. / 

 fide JefEr."
