List of land and freshwater Shells collected by 

 Mr. Osbert Salvin in Guatemala in 1873-4.— By Dr. E. 



von Martens, C.M.Z.S. 



P.Z.S. 1875, part iv, pp. 647 — 9. 



A list of thirty-two species is given; one of them being new, is 

 characterized under the name of Ifelicinaanozona, "Hab. Vicinity 

 of Coban, Central America. 



H. anozona, Martens, is allied to H. fnlva, D'Orb., from Bolivia, 

 and to H. rotunda, D'Orb., from Ihe West Indies ; the first is 

 flatter, larger and differently colored, the latter has no spiral 

 sculpture and a much thinner peristome. 



On the Generic Peculiarities of the distinctively 

 Madeiran Achatinas of Lowe. — By Rev. R. Bo og Watson, 

 F.R.S.E., F.G.S. 



P.Z.S. 1875, part iv, pp. 677 — 80, with woodcuts. 



A new genus Lovea is established and its differences from 

 Achatina characterized as follows: — "The mantle extends beyond 

 the edge of the aperture all round, it is thinly spread over the out- 

 side of the shell, and extends like a tongue backwards behind the 

 posterior corner of the aperture. 



The tail carries a mucous gland and is abruptly truncate. The 

 genus thus bears to Achatina the same relation that Arion does to 

 Li max and Nanina to Helix." 



All the members of the genus have an highly polished shell, 

 caused by the perpetual movement upon it of the overlapping 

 mantle, especially of its posterior elongation, a movement also 

 eminently characteristic of Nanina. 



The jaw is horny, light-brown, crescentic, with numerous small 

 converging ridges, one of which forms a distinct median line 

 The edge is not toothed, but forms a continuous curve. The
