TURBONILLA (MORMULA) ESCHSCHOLTZI, new species. 

 Plate XLV, tig. 10. 



Shell large, elongate-conic, brown, having three obscure bands of 

 dark 1)rown, one of which is at the summit, another at the perij)hery, 

 while the third is halfway between these on the exposed portion of 

 the whorl of the spire. Nuclear whorls decollated. Post-nuclear 

 turns moderately rounded, ornamented by low, rounded, rather dis- 

 tantly spaced, slightl}^ protractive axial ribs which become weakened 

 and somewhat flattened as they approach the appressed summit, and 

 many fine lines of growth both on the ril)s and in the intercostal 

 spaces. In addition to the axial sculpture the whorls are crossed b}' 

 twelve deeply incised, somewhat irregularly spaced spiral lines, the 

 raised spaces between which are again divided bj- many tine strife. 

 All the spiral markings pass over the intei'costal spaces and the ribs. 

 Periphery of the last whorl obscurely angular, marked by the feeble 

 continuations of the ribs which vanish immediately ])elow the periph- 

 ery and the usual fine lines of growth and spiral striation. Base 

 rather short, well rounded, brown, with a narrow whitish band about 

 the umbilicus, marked by closely spaced continuous wavy spiral stria- 

 tion, which varies in strength, several finer strife alternating with the 

 stronger. Aperture subquadrate, outer lip thin, showing' four narrow 

 dark-brown Itands within, upon a lighter background — the.se are the 

 three already referred to — and a fourth one on the base adjoining the 

 periphery; columella almost vertical, slightly twisted and revolute. 



The type (Cat. No. 196241, U.S.N.M.) was collected by Rev. G. W. 

 Taylor, at Cartel Bay, British Columbia; it has 11 post-nuclear whorls 

 (the nucleus and probably three of the post nuclear whorls being lo.st), 

 and measures: Length 13.3 mm., diameter 4 nun. Another specimen 

 from the same localit}^ is in the Taylor collection. Three additional 

 lots were collected by him in British Columbia; one, a fragment, from 

 we.st of Rose Spit, Queen Charlotte Islands; 6 at Departure Bay, one 

 of which is Cat. No. 196242, U.S.N.M.; 15 at Port Simpson, 5 of 

 which are Cat. No. 196243, U.S.N.M. No. 196242 is the largest 

 specimen, it has 12^ whorls, having lost the nucleus and probably the 

 first three of the succeeding turns and measures: Length 17.S nmi., 

 diameter 4.5 mm.
