100 CARELIA. 



This species seems to resemble F. splendida (Anton) in 

 contour, but according to Anton that has but 5 whorls. 

 Pfeiffer's splendida is, according to the figure, a more conic 

 shell. Under the circumstances it is probably best to give a 

 recognizable account of the form before me, leaving the ques- 

 tion of its possible identity with one or other of the forms 

 described as splendida for future decision.

The shell is imperforate, oblong-turrite, solid; embryonic 

 shell conic, with slightly obtuse apex and flat whorls; first half 

 whorl smooth, the next whorl or two with sculpture of arcu- 

 ate axial striae or riblets, which are often split; neanic and 

 adult stages irregularly striate or nearly smooth, sometimes 

 with spiral lines or ribs, the whorls slightly convex, or with 

 one or two spiral carinas. Aperture ovate ; outer lip simple 

 and acute; columella concave, obliquely or vertically trun- 

 cate below, and bearing a small callous lamella. Axis slender 

 and nearly straight in the inner whorls, becoming sinuous in 

 the last. 



Soft anatomy unknown, except the jaw and teeth, which 

 have been described and figured by Binney. The jaw of 

 C. bicolor (pi. 21, fig. 12) "is low, slightly arcuate, with but 

 little attenuated, blunt ends; anterior surface with ten stout 

 ribs, denticulating either margin. 



"Lingual membrane of C. bicolor (pi. 21, fig. 11) long and 

 narrow ; teeth 37,1,37, of same type as in the species of
