Shell thin, polished, yellowish -white, finely striated ; posterior 

 portion with brown lines in bundles crossing and connecting 

 with each other. 



Hah. — Sandwich Islands, dredged in 12 fathoms, outer har- 

 bor of Honolulu. 



This is one of the most beautiful species of the Genus 3/o(??'o?a of 

 Lam. The peculiar color and fine brown markings are sufficient 

 characteristics of the species, which otherwise is most simple in 

 its characters. Only a solitary specimen was dredged in the 

 outer harbor of Honolulu, and I take pleasure in attaching to it 

 the name of one of our most industrious and enterprising living 

 naturalists. 



Proto Cornelliana, Newc. — Plate 17, figure 3. ' 



P. testa elongata, solida, alba, nitida, sublente longitudin- 

 aliter costata et transversim subtiliter striata ; apice sinister ; 

 anfr. octo, orbiculatis, quarto et septimo cum obscura varice ; 

 sutura fere transversa sub-profunda, lata, et obscure dentata ; 

 apertura rotunde ovata ; labro crasso et obscure bilabiate. 



Long. 4-10 pol. ; Lat. 1-10 pol. ; apertura 1-20 pol. 



Shell elongate, solid, white, shining, under the lens longi- 

 tudinally ribbed and very finely transversely striate ; apex sin- 

 istral ; whorls 8, rounded, the 4th and 7th with an obscure varix; 

 suture nearly transverse, wide, rather deep and obscurely den- 

 tate ; aperture entire, roundly ovate ; lip thickened and indis- 

 tinctly bilabiate. 



Remarks. — The genus Proto was made in 1 824, by Defrance, 

 for the reception of a species [P. Marascliini^) with claims more 

 decided, so far as the shell is concerned, than hundreds of the re- 

 cently manufactured artificial Genera which encumber our pre- 

 sent nomenclature. Its " restoration," or re-union with Turri- 

 tella, as declared by Chenu, is not fortunate, for its affinities 

 are much nearer Ohemnitzia {Turbonilla) than to Turritella. 

 I have taken the liberty of attaching the name of Mr. Cornell 

 to this beautiful species, which was dredged in twelve fathoms 

 of water outside the reef near Honolulu, Sandwich Islands.
