This species has very much the look of a small Fusinus of the typical group. 



Turris (Surcula) dolenta Dall, n. sp. 



Shell elongate, acutely fusiform, white, with nine rather rounded whorls follow. 

 iiig the (lost) nucleus ; general aspect recalling the preceding species but larger, 

 with a proportional ely more swollen body whorl ; fifth whorl with nine, ninth with 

 nine short protractive axial ribs confined to the shoulder and periphery ; the 

 whorls are covered with spiral threads of which two marginating the suture and 

 two on the periphery are more conspicuous than the rest, but not perceptibly 

 nodulous ; between the peripheral cords there are, on the later whorls, from two 

 to four minor threads ; on the base of the last whorl there are six or seven 

 major, as many intermediate, and about a dozen minor threads ; the suture is very 

 closely appressed and the anal fasciole nearly free from axial and with only very 

 fine spiral threads ; anal sulcus wide and deep begiuniug at the suture ; outer lip 

 thin, much produced, roundly arcuate to the somewhat coastrictcd base of the 

 whorl ; aperture, including the canal, as long as the spire ; pillar smooth, white, 

 not callous ; obliquely attenuated in front, the canal ample ; flaring a little in 

 front ; axis impervious ; the back of the canal closely spirally threaded ; length of 

 shell, 36 5 ; of aperture, 19.25 ; max. diam. of last whorl, 13.0 mm. 



U. S. S. " Albatross," station 2804, in Panama Bay, in. 47 fathoms, mud ;

"With extremely similar sculpture this differs from T.fusinella in size and in 

 the proportions of the whorls, wliich are also of a dull white surface, while T. 

 fusinella is polished and shows indications of a color baud which in some speci- 

 mens may be well marked. 



Turris (Surcula) armilda Dall, n. sp. 



Siiell small, delicate, fleshy white, obscurely baiulcd with brown, a pale belt on 

 the last whorl just in front of the periphery; whorls eight excluding tlie (lost) 

 nucleus; spire acute, slightly shorter than the aperture including the canal; 

 whorls with a conspicuous shoulder, above which a slightly concave spirally stri- 

 ate anal fasciole extends to the appressed suture, which on the last whorl or two 

 shows indications of a marginal lliickcning; axial sculpture of (on the last whorl, 

 about fifteen) protractive short riblcts withsubcqual or slightly shorter interspaces
