lip crenulate, ridged within, with a shallow, wide sinus ; colu- 

 mellar lip with a median callosity. Length, 9 mill. 



Ceylon. 

 Described from a single specimen. 



D. BELLARDI, Jousseaume. PI. 34, fig. 8. 



Shell white, spirally costate ; outer lip crenulated, with a 

 shallow sinus near the suture ; columellar lip with a median pli- 

 cation. Length, 11 mill. 



Hab. unknown. 



The above three species are, judging from the figures, described 

 from immature and imperfect, possibly water-worn specimens, 

 so that it is not easy to compare them with previously described 

 species. There are a number of spirally ribbed species described 

 by Smith and older authors to which these may be approximated, 

 but in the absence of material, no definite result is practicable. 

 The practice of describing unique and imperfect specimens can- 

 not be too strongly condemned. Desire for scientific renown 

 will continue to enlarge our synonymy, until some method can 

 be devised, by which no man's ambition can possibly be gratified 

 in the making of generic and specific names. Although Dr. 

 Jousseaume has furnished the text of this sermon, it is not 

 intended to signalize him as a principal offender ; much greater 

 men in fact the greatest conchologists are equally in fault in 

 their desire to write nobis as frequently as possible. 



DRILLIA LIMONITELLA, Dall. PL 34, fig. 6. 



Small, thin, translucent, lemon-yellow, very faintly narrowly 

 brown-banded on the periphery and below it on some specimens, 

 the columella also brown-tinged ; whorls turreted, nodulated at 

 the periphery by about a dozen ribs, which extend across the 

 shoulder to the suture, spiral sculpture very fine and close; outer 

 lip slightly thickened, with a distinct, rather broad, shallow 

 sinus. Length, 6*75 mill. 



Cedar Keys, Fla., on mud flats between tides (Hemphill). 



COLUMBARIUM PAQODOIDES, Watson. 



This species, recently described as a Fusus, is probably only 

 a variety of C. Pagoda, Lesson. It is unfigured.
