HELIX. 



H. MARIANNE Kobelt, 1880. .PL 60, figs. 92, 93 ; pi. 65, figs. 57, 

 58. 



Of this species, which was at first identified with the long-lost H. 

 circumornata of Ferussac. Dr. Kobelt says : My examples show three 

 bands of square reddish brown markings, which have their longer 

 dimension in the direction of the incremental striae ; the middle ones 

 are much wider than the two outer, and often formed by the co- 

 alescence of the second and third. The arrangement of the markings 

 is remarkably regular, as the figure of Ferussac indicates. The 

 sculpture is like that of If. carseolana and also the form of the whorls, 

 except that these are more raised, 'and no angulation is visible. The 

 aperture more widely rounded, and relatively shorter than in the 

 typical carseolana ; the terminations of the peristome are much less 

 approaching, and the basal margin is less thickened by the callus. 

 The peristome, too, is of a rather bright reddish-brown color, and 

 only its very edge is white. (Icon. 1. u. suss. iv. Moll. Eur., etc., 

 v.,p. 77.) 



Separated from H. surrentina by the greater elevation, and the 

 inflated whorls, which are shouldered at the suture; from H. carse. 

 olana by the closed umbilicus and the brown peristome. Its home 

 is eastward from the Appennines, in that Apulian outlier of the Ap- 

 pennines known as the Murgie. (Kobelt in Icon, etc., vii, p. 9.) 



This is the H. circumornata of Kobelt, (1877), not of Ferussac. 



Var. PEUCETANA Kobelt. PL 65, figs. 59, 60. 



Nearly unicolored yellowish-brown above, the whitish ground-col- 

 or of the type wholly lost; markings wholly coalescent, except for a 

 dark subsutural zone and the second and third bands visible behind 

 the aperture ; fourth band sharply defined. 



H. OIKCUMORNATA Ferussac. PL 60, figs. 81, 82. 



Imperforate, globose-depressed, glabrous, white, encircled by a sin- 

 gle central fascia, and three series of orange-brown spots ; whorls 

 four, planulate, the last inflated ; aperture lunate-elliptical, brown 

 within ; peristome subreflexed. (Fer. et Desk., Hist., i, p. 122.) 



Diam. 17, alt. 9 mill. 



The original figures of Ferussac are copied on my plate. The 

 species has not been satisfactorily identified with any of the Italian 

 Iberus. Dr. von Martens has described and figured specimens of 

 an Iberus similar to H. mariannce as this species ; but the correct- 

 ness of his identification is extremely doubtful. See Conch. Mlttheil., 

 i, p. 19.
