62 ODONTOSTOMUS. 



pupoides (inflata Wagn.) as a variety. It may possibly be a large 

 form of this species, but the figure is insufficient for identification. 

 It has been called Pupa listeri by GRAY, Ann. of Philos. n. ser., ix, 

 412, and Cyclodontina listeri by BECK, Index, p. 88. 



Helix ( Cochlodonta] brasiliensis Ferussac, founded upon a -figure 

 in Mawe's Travels, is very likely the small typical form of 0. inflata ; 

 but there is no description, and the figure is not absolutely conclu- 

 sive. I think a reincarnation of this phantom inadvisable and in- 

 deed unwarranted. May it rest in peace ! 



0. SCABKELLUS ('Anthony' Dohrn). PI. 11, figs. 54, 55. 



Shell compressed-umbilicate, fusiform-turreted, thin but rather 

 strong ; flesh-tinted between strong, close white ribs as wide as their 

 interstices. Whorls 9-10, but slightly convex, the last having two 

 pits behind the outer, one behind the basal lip, and frequently a 

 slight groove below and accompanying the latter end of the suture, 

 which is there somewhat channelled. Aperture small, obstructed by 

 7 teeth : a compressed parietal lamella. A strong columellar lamella, 

 bent at a right angle below, a small compressed basal fold, and four 

 compressed folds within the outer lip, the largest one (upper palatal) 

 median, lower palatal rather strong, nearly basal in position, two 

 small suprapalatal folds, the upper one defining a sutural groove 

 which notches the termination of the lip ; columellar margin dilated, 

 distinctly grooved at its root. 



Length 19-23, diam. 7^, aperture 7J mill.

B. scabrellus Anth., DOHRN, Jahrb. d. D. Malak. Ges. ix, 1882, 

 p. 106 (under sp. 15 ; no description), pi. 3, f. 9. 



The relationship of this species to 0. inflatus is seen in the grooves 

 cutting the ends of the lip, and the tooth arrangement, but it is dis- 

 tinct in the strong sculpture of white riblets on a fleshy or gray 

 ground. I can find no description of the species by Anthony, whose 

 name scabrellus is known by museum labels. The specimens de- 

 scribed above and drawn in fig. 55 were received from Anthony, and 

 bear his autograph label.

 and pitted surface. Teeth various, but the parietal lamella is com-
