142 BULIMULCS. 



Bulimus cretaceus PFR., P. Z. S., 1854, p. 123 ; Monogr. iv, p. 396. 



The figures represent specimens received from Mr. Fulton, from 

 the locality first given above. That mentioned by Pfeiflfer was evi- 

 dently a guess. It has not before been figured. 



The sculpture consists of fine, crowded growth-wrinkles cut into 

 long granules arranged in spiral series. Usually these granules are 

 quite weak, and scarcely or barely visible to the naked eye. The 

 apical whorls have a dense thimble pitted pattern, much like that of 

 B. corceformis (vol. xi, pi. 26, f. 85), and B. barom. The color 

 varies widely. On a white ground there are five brown bands and a 

 brown umbilical patch, in some specimens; in others these bands 

 may be almost wholly wanting, while still other examples have them 

 confluent on the last whorl, or the whole surface may be dull brown- 

 ish. The aperture may be either purplish-brown or white within, 

 and the very broadly reflexed lip varies from wholly white to deep 

 brown with a white border. The umbilicus is ample. Specimens 

 measure: 



Length 41, diam. 26, longest axis of aperture 25 mill. 



Length 40, diam. 23, longest axis of aperture 24^ mill. 



Length 24^, diam. 2H, longest axis of aperture 22 mill. 



Length 31^, diam. 17^, longest axis of aperture 17^ mill. 



B. BAKONI Fulton. Vol. xi, p. 172. 



This species is a Scutalus, close to B. cretaceus, B. corceformis and 

 B. proteiformis. 



B. COR^FORMIS Pilsbry. Vol. xi, p. 15, pi. -J5, f. 61 ; pi. 26, f. 85 ; 

 pi. 30, f. 10-13. 



B. TUPACII (Orb.). Vol. xi, p. lit. 



Dr. A. Stiibel took a specimen at Yrupana, Bolivia. It is short, 

 like that figured by Reeve. (Martens, Conch. Mittheil, p. 157.) 



Information on Argentine specimens from the Sierras of Tucuman 

 and Salta is given by Doering, Periodico Zoologico ii, pp. 256-258 

 (1877).
