114 THE NAUTILUS. 



race (grandior, n. var. ), max. diam. 29-30.5 mm. In this 

 peculiarity the fossil L. undata falls in line with other species, 

 thus P. bowditchiana is a sort of large edition of the common 

 living P. punctulata (Shy.) 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 Limax maxi- 

 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 whorls 

 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.
