106 HELIX-EUHADRA. 



streaks. The forms included in the above synonymy do not seem 

 to possess even varietal characters. Figure 4 of plate 28 is from 

 the original illustration and Crosse. Figures 6 and 7 represent 

 H. amalice Kobelt. Figures 1, 2, plate 29, are H. congener Smith. 

 The specimens before me are from the Hakone Mountains. 



H. SEROTINA A. Adams. Un figured. 



Shell subglobose, broadly perforate ; spire elevated-turbinate, apex 

 obtuse ; whorls 6, convex, obliquely grooved (grooves unequal) and 

 decussated by most minute close revolving strife ; base convex ; aper- 

 ture lunate ; peristome expanded, reflexed, white within, thickened, 

 dilated at the umbilicus, straw-colored, sometimes ornamented with 

 a transverse reddish-brown band. (Ad.) 



Sagaleen, near Cape Notoro, Japan. 



H. serotina AD. Ann. Mag. N. H. 1868, 4th ser., vol. i, p. 461. 

 PFR. Monogr. vii, p. 374. 



A pretty species, orange or deep straw-colored, very much resem- 

 bling in general appearance the bright yellow varieties of H. horten- 

 sis. I found it living in the dense thickets of bamboo near the shore.

H. LEWISII E. A. Smith. PI. 29, fig. 6. 



Shell dextral, conoidal-globose, narrowly umbilicate, obliquely 

 striate, white covered by a thin buffish-olivaceous epidermis, and 

 encircled at the periphery by a narrow brown band. Whorls 6^, a 

 little convex, sensibly increasing, the last rounded, descending a 

 short distance in front ; aperture oblique, white within ; peristome 

 expanded all around ; columellar margin tinged with dull rose, 

 broadly expanded and reflexed above. (Smith.) 



Alt. 24, greater diam. 35, lesser 29 mill. 



Japan. 



H. lewisii SMITH, P. Z. S. 1878, p. 495 (wood-cut). 



Perhaps the most closely allied Japanese species to this one is H. 

 miranda, A. Adams. From it H. lewisii differs in having a more 

 conical spire, a narrower umbilicus, finer oblique stria?, and no spi- 

 ral sculpture. The oblique strire at the suture are rather deeply in- 

 cised and more crowded than on the other parts of the whorls, many 

 of them extending only about a line from the suture and then grad- 

 ually fading away. The first four whorls differ from the last two in 

 being obliquely punctato-striate, instead of exhibiting an ordinary 

 striation.
