242 FAUXULUS. 



The lamellae and plicae are more developed than in typical 

 Fauxulus, from which Tomigerella differs also in shape, color 

 and texture. 



3. FAUXULUS CRAWFORDIANUS Melvill & Ponsonby. PI. 41, 

 figs. 1, 2. 



Shell narrowly rimate, cylindric-fusiform, smooth, some- 

 what shining, thin, brown. Whorls 8-9, the apical mamillate, 

 the rest impressed at the suture, nearly smooth, under a lens 

 very obliquely longitudinally striate, the last shorter below 

 the periphery. Aperture rotund; peristome white, glossy, 

 reflected, continuous, six-plicate : two scimitar-shaped, pari- 

 etal plicae, one inferior acute, entering, two labial [palatal], 

 entering deeply, the upper one oblique, the lower nearly 

 straight ; basal tooth subinternal, mammiform, columellar fold 

 scimitar-shaped, deeply entering. Length 8, width 3.75 mm.

Mr. Burnup 's figures of this species are copied. He writes : 

 ' ' Melvill and Ponsonby say of this species : ' Allied to P. lay- 

 ardi Bens ' ; but it is easily distinguishable by its stouter 

 form, less ventricose whorls, shallower sutures, more regu- 

 larly conical spire, less mammillated apex, rather smoother 

 surface, less effuse peristome, and by the absence of the sev- 

 enth, minute, plait to be seen, in P. layardi, at the junction 

 of the parietal wall with the columella. The arrangement of 

 the other peristomatal processes is practically identical in 

 both species. The original figure is defective in form and 

 deficient in detail, so I herewith offer new figures drawn from 

 the co-type in Mr. Ponsonby 's collection, kindly lent to me 

 for the purpose. Mr. Ponsonby has compared my figures 

 with the type in the British Museum, and finds that they cor- 

 respond accurately, except that the callus in the type is not
