70 HELIX-HELICOPHANTA. 



dirty white, narrowly expanded and subreflexed, the columellar mar- 

 gin more broadly reflexed, becoming adnate at the umbilical region, 

 where is expands into a broad whitish callus plate, a thinner con- 

 tinuation of which extends across the body to the upper angle of the 

 aperture. The inner edge of the columella is concave.

H. goudotiana REEVE, Conch. Icon., t. 38, f. 174, b, not of 

 Ferussac ! 



The specimen described above is drawn on pi. 66, fig. 61 ; Reeve's 

 illustration of the same form is given on pi. 11, fig. 39. Compar- 

 isons should be made with H. oviformis Grat. (pi. 66, fig. 60), and H. 

 Goudotiana Fer. (pi. 9, fig. 21). The former I have assumed to be 

 a shell of immature growth, although it is obvious that Grateloup 

 had more than one specimen before him. It is narrower than my 

 H. phenax, with decidedly different columella ; the true Goudotiana 

 Fer. (non Reeve nee Pfr.) is a smaller shell, with more tortuous col- 

 umella, and as Deshayes states and the figures plainly show, the 

 columellar lip is more narrowly reflexed than the outer lip. The 

 wrinkling of the surface also separates it, phenax being entirely 

 free from malleation or wrinkling. 



Another shell which may be referred to H. oviformis or H. phenax 

 as a variety is figured on pi. 66, fig. 59; it agrees with phenax except 

 in the following characters : it is more lengthened, proportionally 

 narrower, the body-whorl less ventricose, and convex instead of flat- 

 tened on the umbilico-basal portion. The columella is more suddenly 

 dilated at the umbilical region. 



Alt. 62, greatest width 47*. Oblique alt. of aperture 50, greatest 

 breadth 37 mill. 



Pfeiffer's figures (in the Conchylien Cabinet, plate 54, figs. 1, 2, 

 " H. Goudotiana") are evidently drawn from a shell of this variety. 



Crosse and Fischer figure under the name " oviformis" a specimen 

 of my H. phenax. (Vide Moll. Madagascar, pi. 1, figs. 5, 6.) 



H. GOUDOTIANA Ferussac. PI. 9, fig. 21. 



Shell oblong-ovate, imperforate ; spire very short, composed of 4? 

 whorls, very rapidly increasing ; color reddish-brown or yellowish, 

 with two narrow encircling zones of deep dark brown. Surface fine- 

 ly granulate all over, and with obliquely descending wrinkles (visi-
