Tornatellina striata. — T. testa acute-turrita, rufo-cornea, minute 

 et impresso transverse striata ; apice acuto ; sutura mediocriter 

 impressa ; anfr. 6 ad 8, ultimas 2-5 longitudinis sequans ; apertura 

 elongate sub-ovata ; columella truncata, excavata, contorta inferiori 

 parte in plicam. 



Hab. Kauai. Insula Sandwichensis. Long. 5 mill. 



Diam. 2 " 



Shell acutely turretted, reddish horn color, minutely and impressly 

 striated transversely ; apex acute ; suture moderate ; whorls six to 

 eight, the last two-fifths of the whole length ; aperture produced sub- 

 ovate ; columella excavated, truncated, twisted below into a fold. 



Retnarks. — This species makes a nearer approach in its general 

 appearance to the Genus Tornatellina than to any other yet con- 

 stituted. Though not answering fully the generic description in 

 the want of a fold or lamellar tooth on the parietal wall, we find it 

 tranferred as in some of the species of the section of Leptachatina 

 (Gould) to the termination of the columella. Two other species 

 have been given from the Sandwich Islands, viz : Tornatellina pepo- 

 num (Gould) and T. Newcombi Pfr., both of which are of differ- 

 ent form from the one now described, and are without the transverse 

 striae characteristic of this last named species. 



Achatinella Anthonii, — A. testa conoideo-ovata, solida, nigrito- 

 brunnea, longitudine striata ; anfr. 6 inflati ; sutura modice im- 

 pressa ; apice obtuso ; apertura oblique ovata, infra sub-angulata ; 

 labium simplex intus crassum ; columella brevis, recta, plica paulu- 

 lum callosa sub media ; infra suturam fascia alba, et regione umbil- 

 icare sordido-alba. 



Hab. Kauai. Long. 15 mill. 



Lat. 10 " 



Aperturre Long. 6 " 



Lat. 4i " 



Shell conically ovate, solid, blackish brown, longitudinally striate ; 

 whorls six inflated ; suture moderately impressed ; apex obtuse ; 

 aperture obliquely ovate, sub-angulate below ; lip simple, thick- 

 ened within ; columella short, straight, with a somewhat callous 

 plication below the middle ; white-banded below the suture, and of 

 a dirty white in the umbilical region. 



Remarks. — Excepting in size, and in being more ventricose, this 

 species makes a near approach to A. nucleola (Gould). It is more 

 than quadruple the size of nucleola, and not acute at the summit, 

 by which it can be at once distinguished from that species. For 

 this and the preceding species I am indebted to the Rev. Mr. John- 

 son, of Koloa. It is named after the eminent Naturalist, John G. 

 Anthony, Esq., of Cincinnati, Ohio.
