A single shell from Onion Creek has a distinct callous prominence 
within the outer lip and a low tooth in the basal lip. Anatomically 
it resembles the topotypes of A. esuritor so far as can be made out, 
the soft parts being mutilated in pulling. The mantle is white within 
the last whorl. 
Group of A. metamorphosa. 
Ashmunella metamorphosa Pils. Pl. IX, fig. 9. 
Proc. A. N. S. Phila., 1905, p. 252, pl. 16, fig. 115 (shell); pl. 22, fig. 8 
(radula); pl. 23, fig. 16 (jaw); pl. 21, fig. 27 (genitalia). 
With one exception the original figures of this species, cited above, 
were taken from one specimen. Fig. 114 of plate XVI (1905) 
represents another shell, probably not conspecific. It is now pro- 
posed to restrict the type of A. metamorphosa to the broken shell 
represented on pl. XVI, fig. 115, the anatomy of which was figured. 
This is No. 88885 A. N. 8. P. 
This shell (pl. LX, fig. 9) resembles A. esuritor in contour. There 
is a deep furrow behind the narrowly reflexed basal and outer lips. 
The outer lip bears a long low callus on its inner edge. Above this 
callus it is brown, elsewhere white. Whorls 6. The surface is not 
well preserved and shows no minute sculpture, bemg somewhat worn. 
Alt. 8.8, diam. probably about 17 mm. It is a fully adult, but not 
old, individual. In pl. IX, fig. 9, the aperture of the type specimen 
of A. metamorphosa is drawn, the former photographic figure being 
unsatisfactory. 
Barfoot Park, collected by James H. Ferriss, February, 1904. 
We have nothing to add to the description and figures of genitalia 
jaw and teeth given in 1905. Having again examined the genitalia 
of the type, we see nothing to indicate that it is abnormal. The 
possibility that it is the 2 phase of a proterandrous form has been 
considered, but the absence of such a condition in the other species 
of the genus makes against such hypothesis. If normal, the genitalia
