226 ASTRALIUM. 



A. GUAI>ALOUPEN>E ( Yosse, 1865. PI. 53, figs. 43-45. 



Shell imperforate, solid, elevated-conic, longitudinally suboblique- 

 ly Avrinkled, reddish orange, marked in places with white and oli- 

 ut u re impressed, irregular ; whorls 6 '*, subplanulate above, 

 slightly concave in the middle, the apical one or two smooth, the 

 following longitudinally plicate, the folds cut in the middle by two 

 impressed spiral lines, projecting at the carinated periphery, and 

 about twenty-three in number on the body-whorl; base nearly flat 

 with radiating stria? and five subgranose line ; aperture oblique, 

 rhomboidal, columella white, arcuate, bidentate at base, umbilical 

 tract pale violaceous, bounded by a plicate cordon. 



Alt, 231, diam. 25 mill. 



Guadaloupe, West Indies. 



Operculum outside convex, with a median rib, minutely granulose, 

 excavated near the middle. 



It is closely allied to A. papillatum P. M., but may be separa- 

 ted by the flatter base and perhaps the number of the basal line. 

 Compare also A cubanum. In the only specimen of this species I 

 have seen (fig. 45) the peripheral tubercles number twenty on the 

 body-whorl. I believe that this species will be found to be a form 

 of A. cubanun or A. papillatum. 



A. OLFEESI Troschel, (18 ?). PI. 57, figs. 47-49. 



Shell imperforate, solid, conic, gray, olive-green and reddish brown; 

 longitudinally plicate, the folds about thirteen in number on the last 

 whorl ; periphery nodulose ; base slightly convex, with four concen- 

 tric lira? ; aperture subtrapezoidal, white ; columella arcuate, bitu- 

 berculate at the base. Alt. 45, diam. 52 mill. 



Brazil (Philippi); Bahia (Clery). 



Figs. 48, 40 are drawn from the original ones. I have seen no 

 specimen corresponding with them.- The variety figured by Kiener 

 (pi. 57, fig. 47) scarcely looks the same to me. It differs in the "less 

 oblique and more numerous longitudinal folds, which are more in- 

 terrupted about the middle and more nodulose above.'' A specimen 

 of this variety before me is marked "West Indies" 



Operculum (pi. 59, figs. 22, 23) oval, granulose outside, strongly 

 ribbed. 



T. saxosus Phil., is a synonym. 

 xV. IMBRICATUM Gmel., 1788. PI. 55, fig. 70. 



Shell conic, solid, imperforate, cinereous or light brownish ; whorls 

 7, planulate above, very obliquely striate, and longitudinally plicate,
