268 DELPIIIXULA. 



DelpJiinus decrepitus and Delpliimis atratus Chemnitz are identi- 

 cal with this species. 



D. martin ii A. Adams, (pi. 66, fig. 19) from Padang differs only 

 in the color. The spines are red or purplish on a pink ground. 



Yar. MELAXAOANTIJA Reeve, 1842. PL 65, figs. 6, 7. 



Whorls rounder, less marinated below than in the type; surmount- 

 ed by a corona of slender long radiating or ascending spines ; um- 

 bilicus wider. 



D. imperialis Reeve and D. distorta Kiener (not Lam. nor Linn.) 

 are synonymous. 



D. SPH/KRULA Kiener. PL 67, fig. 5 ; pi. 68, fig. 20. 



I know this form only by the description and figures .given by 

 Kiener. The latter are copied on my plates. In the simple, appar- 

 ently very regular spines, the form is different from any specimens 

 I have seen. 



In til an Ocean. 

 D. DISTORTA Linn, 1758. PL 65, fig. 8 ; PI, 68, figs. 12, 13. 



In general form similar to D. Incut iata. Upper surface of whorls 

 radiately conspicuously plicate, the folds terminating in solid knobs 

 or short spines at the carina ; linn? rather coarser than in laciniata ; 

 base of body-whorl rounded or only obtusely carinated ; the sculpt- 

 ure and color of the umbilical area not notably different from that 

 of the whorl outside ; color white or pink, the lira . .-^/.//rx and scales 

 deep crimson; size smaller than laciniata. Alt. 30, diam. 40 mill. 

 or less.

This is the Turbo distortus of Linn., Delphi nala distorta Lam., 

 and D. rngosa of Kiener's plates. 



A;-: far as my material allows me to judge, this form does not in- 

 tergrade with D. laciniata. 

 D. TYRIA Reeve, 1842. PL 66, figs. 12, 13. 



In general form like D. laciniata. Whorls ungulate at the shoul- 

 der, rounded or obtusely angular around the umbilicus, covered all 

 over with densely and acutely squamose lira? ; upper surface of 

 whorls plane or gently radiately undulating; color white, the um- 

 bilical region and a subsutural spiral band, deep purple or purplish 

 crimson. Alt. 45, diam. 50 mill.

The fine uniformly scaled sculpture will distinguish this beautiful 

 species.
