444 PROCEEDINGS OF THE ACADEMY OP [1896. 



by fine, often granulose spirals, which are swollen where they cross 

 the riblets ; aperture small, throat yellowish, the pillar white, widely 

 reflected without any terminal plait or callus, outer lip thickened, 

 somewhat expanded, continuous with the pillar and a slight callus 

 on the body. Length 12, breadth 5 mm. 



James Island, 'U. S. Fish Commission. 



This interesting species was obtained on James Island in small 

 numbers, one specimen fresh but none living, the one figured has 

 rather sparser ribbing than the best preserved specimen. Most of 

 them are bleached white. The shell appears to be intermediate in 

 character and size between B. sculpturatus as figured, and B. rugi- 

 ferus Sby. It was at first referred to the latter species, but further 

 study showed B. nesioticus to have two whorls less in the same 

 length and to be a perceptibly stouter shell. 



Bulimulus (Nsesiotus) Reibischi Dall. Plate XVI, fig. 4. 



Buliiimhcs {Nasiottis) Reibischi T)di\\, Nautihis, viii, p. 126, March, 1895. 



Shell elevated, slender, with nine whorls of a pale ferruginous 

 color and rather solid consistency ; sculpture like that of B. nesioti- 

 cus but rather more closely ribbed ; the suture distinct, somewhat 

 appressed, whorls little inflated but not flattened ; umbilicus a mere 

 chink ; aperture oval, higher than wide, rounded in front, the pillar 

 simple, the margins thickened but not reflected; length 11.0, diame- 

 ter 2.5 mm. 



Indefatigable Island, two specimens, U. S. Fish Commission. 



This shell, though shorter, is intermediate between such forms as 

 B. chemnitzioides and the more normal Niesioti. It is named in 

 honor of Herr Paul Reibisch, of Dresden, who recently worked up 

 the land shells collected by Wolf in these islands, in a paper to 

 which I have made frequent reference. 



Bulimulus new species. Plate XV, fig. 15. 



Shell of about nine whorls, small, slender, with flattish sides, 

 almost cylindrical, transversely finely wrinkled, suture distinct; 

 aperture small, the outer lip sharp, the pillar lip short, broadly re- 

 flected, without plait or projecting callus ; length 11.5, breadth 2.5 

 mm. 



One specimen found on James and two on Indefatigable Island,
