Meta perplexabilis, n. sp. 

 Plate 15, Figures 4, 5 



Shell with a slight general resemblance to M. epamella Du- 

 clos; entirely smooth except for faint growth striae and a vary- 

 ing number of incised lines and corresponding ridges on the an- 

 terior part of the body whorl; nuclear whorls two, swollen, glassy; 

 post-nuclear whorls five, slightly truncated at their posterior 

 margin, and so coiled as to project a trifle above the suture, 

 rendering it sub-canaliculate; over the last half of the body 

 whorl the suture droops then suddenly rises abruptly near the 

 aperture; inner lip of adult shells with a thin callus through 

 which the spiral threads of the body appear as rugosities; outer 

 lip with a slight external thickening, a thin margin and with about 

 sixteen lirse within; but immature shells have a smooth 

 outer lip. Length of shell 13, greatest width 6 mm. 



This perplexing shell seems nearest to the genus Meta. It 

 resembles a young Strombus in general form.

We are greatly indebted to Dr. R. Bullen Newton of the 

 British Museum for his kindness in sending us photographs of 

 this perplexing, unfigured species. Dr. Newton writes, ' ' I have 

 critically examined Sowerby 's Columbella haitensis consisting of
