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 3Iodiola of 

 Lam, The peculiar color and fine brown markings are sufiicient 

 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 transversira 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 bilabiato. 



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 1824, by Defrance, 

 for the reception of a species [P. Maraschim,) with claims more 

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

 cently manufactured artificial Genera Avhich encumber our pre- 

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

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

 are much nearer Chemnitzia {Turhonilla) 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.
