Long. 1-6, lat. 2* poll. . 



This species bears a general resemblance to the last, though it 

 may easily be distinguished by its more elevated spire and the ab- 

 sence of an umbilicus. Besides the lighter-coloured band, the shell 

 is usually mottled with paler light-brown markings. A variety oc- 

 curs of a much darker colour, but similarly marked.

This species is most like H. Coccomelos, but may be distinguished 

 from that by its thin, scarcely reflected outer lip. Two varieties in 

 colour have been found, one of which is of a very dark chocolate- 

 brown, and the other of a pale yellowish brown. Another variety, 

 very much resembling this last, has been found at Lobock, in the 

 island of Bohol, which differs only in the lip being rather more re- 

 flected.

Syn. Helix galactites, Lam. (Hist. Nat. des Anim. sans Vert. vi. 

 part 2, p. 69. April 1822). 



Helix mirabilis, De Ferussac (Hist. Nat. gen. et part, des Mol- 

 lusques Terr, et Fluv., t. 31, f. 4, 5, 6. 1819). 



A representation of this fine species, without the epidermis, was 

 published by De Ferussac in 1819, under the name of Helix mira- 

 bilis-, his name is therefore here adopted. But Lamarck in 1822, 

 although he quotes De Ferussac's name and plate, has given it the 

 name of H. galactites, which of course must give way to De Ferus- 

 sac's. 



It appears extremely probable that both Lamarck and De Ferus- 

 sac have confounded with this species a variety of Helix metaformis, 

 De F., the latter author having figured a var. of that species under 

 the name of H. mirabilis, var. See his Tab. 104, f. 6 et 7, and La- 

 marck, describing his var. (3. as '*■ testd superne in conum elongatd."
