Girasial problematica, Fer., Hist. Moll. ii. J)6. Habitat? 



" Shell yellow, convex externally, concave internallj% like a half 

 eggshell." — Deshayes, from Fe'russac's figure. This is very unlike 

 the type. 



In the Appendix to Adams's Gen. Moll. p. 640, it is stated that 

 Dr. Gray, in a communication to the author, proposed that these 

 two last species should be placed in another new genus, Rigasia ; and 

 on the same page G. hookeri is put into Cryptella, a Canary-Island 

 form with which it can have no possible affinity. 



Parmarion, Fischer ^ 



Dr. Semper, in his fine work, Reis. Arch. Phil. p. 9, places in 

 Farmarion two specimens, j';wp«7/a?75, Humbert (problematica, Fer.?) 

 from Java, and extraneus, Fer., obtained through Ilerr Pierre, and 

 taken by him in Calcutta. I am in great doubts as to the identifi- 

 cation of the latter species, which Semper figures on plate i. fig. 5. 

 Mr. Nevill thinks it is Helix bensoni of Lower Bengal. No forms 

 like tlie Khasi-Hill G. hookeri have been taken in Calcutta. If it 

 was found in the Botanical Gardens there, it may have been brought 

 from up the country in baskets of plants. Several imported species 

 have been in this way introduced there from time to time ; and some 

 may have become established. I do not think myself it is H. ben- 

 soni ; the shell is too much covered with the mantle, especially for 

 a spirit-specimen. 



In Nevill's Hand-list of the Indian Museum, Calcutta, p. 13 

 (18/8), in Parmarion he includes two species of typical Girasia 

 from the Khasi Hills, croceus and brunneus, and creates a new sub- 

 g(inMS,Austenia (type Fitrhia c/igas oi Benson, from the Khasi Hills), 

 to include all those species with better-developed shells, which could 

 not be placed in Heticarion, and which I had pointed out were dif- 

 ferent from Theobald's slug-like forms known to us then as Iloplites. 

 He included in this group Iloplites magnijicus, resplendens, peyuensis, 

 solidus, auriformis, heteroconcha, and two others unnamed from Dar- 

 jiling. 



I had myself brought home from India a good many specimens in 

 spirit ; and I have lately received from Mr. Ogle, of the Topogra- 

 phical Survey, to whom my very best thanks are due, another lot 



1 Parmarion, Fischer, Actes Soc. Linn. Bordeaux, 1855. (The paper bears 

 date Juue 1855, the part loth March, 1856 ; so that Mr. Gray's title has 

 priority.) 



Fischer places in it the following species : — 



infimatus, Fer. (Gray, Fig. Moll, plate 286. fig 1). Hab.? (Placed in 

 Britsia, by Gray.) 



extraneus, Fer. (Gray, Fig. Moll, plate 286. fig. 2). Hab. ? 



mngianus, F6r. Bourbon and Madagascar. (Placed in Bmsia ? by Gray.) 



2}roblcma(icus, F^;r. (Gray, Fig. Moll, plate 286, fig. 4). Hab. ? 



From the drawing of infimatxis, by Feriissac, one would be led to suppose 

 that the shell is very rudimentary, and entirely concealed by the mantle-lobes. 

 Unfortunately the habitat of this species and extraneus is unknown. T, how- 

 ever, should place in Fischer's genus all those species in which the shell is 

 so little developed, and take as our N.E.-fruuticr type, P. ruhrimi, G.-A., from 

 the Naga Hills (J. A. S. B. 1875, p. 6, pi. ii. fig. 4), which will require hereafter 

 a close comparison with the Javan forms.
