tracted anteriorly, ^^•iclely open ; outer lip rounded, simple, 

 without a sinus; inner lip strongly curved, and simple. 

 On the spire whorls are about lo strong spiral liree, 

 separated by slightly narrower grooves; these lir^ con- 

 tinue over the body whorl almost to its base. 



Length, 9.4 m.m.; breadth, ^.t, m.m. 



Locality : Type from 40 fathoms three miles east of 

 Schouten Island,- with one other, and from 80 fathoms 

 one example; also from 100 fathoms seven miles east of 

 Cape Pillar three imperfect. 



This is a larger and more solid shell than our other 

 members of the genus; it cannot be considered a typical 

 species, and might perhaps be as well placed in Dono- 

 vonia; it much resembles in form 1\L pallidula Hedley 



TURRITELLA :\IICROSCOPICA, X.S. (PL. XV., 

 FIG. 2^). 



Shell minute, straight, rather blunt; colour yellowish 

 brown, smooth, and shining; whorls 8^, rounded, in- 

 cluding a protoconch oi lYi whorls, the last turn of which 

 forms a small rounded tip ; the lower has a simple groove 

 round the periphery. The spire w horls are encircled by 

 TWO strong grooves, one at the periphery and the other 

 a little above the suture, and on the upper part by a slight 

 depression; the intervening raised portions are somewhat 

 flattened; aperture subquadrate; outer lip thin, dentated 

 ])y the sculpture, which show^s through the shell within 

 the mouth; columella arched and reflexed; rounded 

 anteriorly. 



Length, 3.5 m.m.; breadth, i m.m. 



Locality : Type from 40 fathoms three miles east of 

 sSchouten Island, vrith 18 others; and in 80 fathoms two 

 examples. 



An exceedingly minute Turritella, being in bulk less 

 than half the size of T. smithiana. The sculpture 

 curiously resembles that of Cingulina insignis found with 

 it, and possibly the slight channeling of the mouth may 

 yet place it with that genus.
