TURRITELLA. 199 



obsoletely granulated ridges, and intermediate fine strife ; whitish, 



boldly longitudinally clouded and strigated with chocolate-color. 



Length, 2-5-4 inches. 



West Indies. 



The difference between this and the preceding species is mainly 

 locality, yet the clouded painting is usually of a bolder pattern. 

 The T. goniostoma and all its varieties might be united with this 

 without injury to science. 



This is T. ierebra, Donovan; T. marmorata^ Chemn., perhaps 

 T. meta, Reeve (fig. 63), and T. imbricata, Linn., figured b}' 

 Reeve as var. elongata (fig. 64). 



T. TiGRiNA, Kiener. PI. 62, figs. 65, 66. 



Whorls 1 8-20, rather narrow, flatly sloping, swollen below and 

 obtusely angulated, encircled by eight to ten riblets and inter- 

 vening close striae, suture deep ; whitish, longitudinally irregu- 

 larly strigate with dark chestnut or chocolate-color. 



Length, 3-4-5 inches. 



Panama to Mazatlan. 



The more scalariform whorls and more definite obliquely 

 longitudinal painting distinguish this from the preceding species ; 

 the upper whorls, also, have no central carina. T. Cumingii, 

 Reeve (fig. 66), is a S3^nonym. 



T. ROSEA, Quoy. PI. 62, figs. 61, 68 ; PI. 61, fig. 59. 



Whorls about 15, flat, the last sharply angled around the 

 base, the angle defined by a rib, above which is another rib; 

 encircled by rather close, raised striae, finer on the base ; yel- 

 lowish, marbled with chestnut, the raised striae usually darker 

 chestnut. Length, 2-2*5 inches. New Zealand. 



T. Uneolata^ Kiener (fig. 68), is described from a light colored 

 or faded specimen. The coloring of none of the specimens 

 before me justifies Quoy's specific name. I think that T. Han- 

 leyana, Reeve (fig. 59), will prove to be a young specimen of 

 this species. 



T. SANGUINEA, Rccve. PI. 62, fig. 69. 



Whorls 18-20, slopingl^' convex to an angle above the deep 

 suture, spirally grooved, witli wider, flat-topped ridges; whitish 

 variegate<l on the ridges with transverse oblong chestuut-colored 

 markings. Length, 2-3 inches. Gulf of California.
