1 lil'i BOTHRIEMBRYON 



VOL. XIII. 



Genus BOTHRIEMBRYON (Vol. xiii, p. 1). 



Kobelt, in the last fascicle of the Conchylien Cabinet, monograph of 

 Buliminus, follows that genus with Bothriembryon (p. 763), which he 

 admits to generic rank. His monograph would be bettered by a 

 knowledge of recent Australian and American work. 



B. MARTENSI Kobelt. PI. 26, fig^. 45, 46. 



Shell with completely closed axis, long ovate, rather thin but solid, 

 irregularly striate-costate, seen under a lens to be encircled by nearly 

 obsolete spiral lines ; brownish, copiously marked with chestnut and 

 buff-white streaks. Spire conic, the apex very obtuse, the three 

 earlier whorls pitted, tip turned in ; suture very finely crenulate, 

 narrowly edged with buff-white. Whorls 6, regularly increasing, a 

 little convex, the three earlier pitted, the third ornamented with 

 regularly-placed, pale-brown, oblique stripes; last whorl four-sevenths 

 the shell's length, slightly inflated, rounded beneath, hardly descend- 

 ing in front. Aperture subvertical, oval, the external streaks show- 

 ing through the blue interior ; peristome simple, unexpanded, the 

 outer margin produced at the insertion, basal margin narrowly 

 rounded, columellar margin nearly vertical, quite narrowly reflexed 

 for a long distance, appressed, completely closing the perforation. 

 Length 42, diam. 23.5, alt. aperture 22.5, width 14 mill. (Kob.').

Bothriembryon martensi KOB., Conchyl. Cab., monograph of Buli- 

 minus, p. 764, pi. 112, f. 3, 4 (August, 1901). 



With the same number of whorls, this species is but two-thirds the 

 size of Panda atomata ; the whorls are more convex, it is completely 

 imperforate, and has only traces of spiral lines. Described from a 

 single specimen. The pattern of the apical sculpture is not described 

 by Kobelt with sufficient exactness to permit positive reference of 

 this form to Panda or Bothriembryon. In the former, granules are 

 arranged in spiral series ; in the latter there are pits in oblique 

 sweeps. From what Kobelt says I would think the species cor- 

 rectly located.
