114 THE NAUTILUS. 
race (grandior, n. var.), max. diam. 29-30.5 mm. In this 
peculiarity the fossil Z. wndata falls in line with other species, 
thus P. bowditchiana is a sort of large edition of the common 
living P. punctulata (Sby.) of Porto Santo. 
At the Mount Church, above Funchal, I found C. lucidum 
alive, and made notes on the animal. The tentacles are dark 
grey, with black basal collar; eyes prominent, black; head and 
foot pale reddish ochreous, suffused with dusky; front of head, 
below tentacles, with about six transverse dusky lines; an 
elongate dark patch on each side above mouth; a large suffused 
rosy area behind each eye, visible when the light shines through 
the animal; sole pale ochreous, not divided, but foot emarginate 
posteriorly. The Mount is about 1900 ft. above sea level. At 
higher altitudes in Madeira snails seem to be very scarce. Thus 
around the Pico do Serrado, at about 3000 ft., the only snail I 
could find was Geomitra calva (Lowe), though I obtained three 
species of slugs. These slugs were Milax gagates, the typical jet 
black form, Arion hortensis (new to Madeira) and Limaxz mazi- 
mus. At lower altitudes the M. gagates are plumbeous. (var. 
plumbea Moquin-Tandon). Many years ago I described M. 
gagates var. maderensis, a dark brown variety from Madeira. It 
is now clear that it is only a color-variation, not in any sense a 
local race. Everything indicates that all the Madeira slugs 
have been introduced, though some of them have been in the 
island a long while. I found Arion hortensis also at Madeira, 
and on the Portella Pass another addition to the fauna, Agrio- 
limax laevis.

ANACHIS MINUTA, N. Sp. 
Shell small, thick, nuclear whorls smooth; preceding whorle 
four in number are cancellated by strong straight longitudinal 
ribs and nearly equally strong revolving ridges, three on each 
whorl. Whorls slightly convex, sutures broad and sunken; 
cancellations equally strong, on the whole length of the shell.
