1853. Chemnitzia varicosa A. Ad., P. Z. S., p. 181, PI. 20, fig. 15. 

 1860. ? Turbonilla decussata Pease, P. Z. S., p. 438. 



Off Honolulu in 6-8 fathoms, dredged by Mr. D. B. Kuhns. Also 

 in the Thaanum-Kuhns collection. Some young specimens were 

 taken at Haena, Kauai, Iw Prof, and Mrs. Bryan. 



The shell is slender, turrited, with long, attenuate spire, cinnamon 

 •colored, or nearly white with cinnamon bands. Nuclear shell of one 

 smooth elevated whorl, the spire exposed, low. Post-nuclear whorls 

 are moderately convex, with sculpture of close, rounded, axial ribs, 

 their intervals deep and equal to the ribs on the upper whorls, about 

 half as wide as the ribs on the last four whorls. There are also 

 swollen white varices as wide as three to five ribs, at irregular intervals, 

 more numerous in the lower whorls; in all 8 in the specimen shown 

 in fig. 5. The axial ribs and varices are crossed by rather strong 

 spiral cords, about 10 between sutures, the fourth from above being 

 a little larger than the others. The last whorl is rounded periph- 

 erally and has a short, convex base. The aperture is trapezoidal, 

 angular at the base of the columella. Columella vertical, with a 

 sharp, very oblique spiral fold at the base. Parietal callous scarcely 

 noticeable. 



Length 22, diam. 4.7, length of aperture 4.2 mm.; 15 post-nuclear 

 whorls. 



Chemnitzia varicosa was described from the ''Eastern Seas." 

 The description and figure agree well with Hawaiian specimens. 



I have not seen T. cornelliana Newc, from Honolulu. 



The subgenus Lancella Dall and Bartsch was founded by W. H. 

 Pease (under the preoccupied name Lancea) for large, varicose 

 Turbonillas having conspicuous vertical and spiral sculpture, a 

 prominent nucleus tilted towards its very low spire, and a small 

 spiral fold emerging near the base of the columella. In this last 

 feature it differs from all other Turbonillas, and perhaps the group 

 should be ranked as a genus. 



Besides the species described or mentioned below, the following 

 belong here: T. elongata Pease (name preoc, = T. peasei D. and 

 B.), the genotype, from Paumotus. T. bella D. and B., of Japan. 

 Also, apparently T. cornelliana Newc, from Honolulu, and possibly 

 T. grandis {Chemnitzia grandis) Ads. and Rve., neither of w^hich 

 I have seen. 

 Turbonilla (Lancella) vitiensis n, sp. PI. XXII, fig. 4. 



The shell is turrited, white; embryonic whorl on edge but leaning 

 towards its spire, which is low. Subsequent whorls with sculpture
