reception, and will perhaps prove to be congeneric with Mas 

 chiropus, lately described by me *, which also has the molar 

 teeth of 3fus combined with an opposable hallux and a general 

 CMrojJodomys- or Vandeleuria-YikQ form. Pending further 

 investigation, however, I prefer to do as I did then, and leave 

 the new form in the genus Mas. 



I have taken the liberty of naming this beautiful little 

 species, which looks as if it would make a most enchanting 

 pet, in honour of Her Highness the llanee of Sarawak, a lady 

 whose interest in the zoology of that country is scarcely 

 inferior to that of her husband the Rajah. 



LVII. — On a Small Collection of Land- Shells from Palawan 

 and Balabac, Philippine Islands. By Edgar A. Smith. 



[Plate XVIII.] 



The British Museum has recently obtained a small collection 

 of land-shells, collected by Mr. A. Everett in Palawan and 

 Balabac. Of the thirteen species it contains five appear to 

 be new. This large proportion of undescribed species is not 

 altogether surprising, as neither of these islands has been 

 thoroughly searched for MoUusca. A list of the known 

 species was given by the Rev. A. H. Cooke in the Proc. Zool. 

 Soc. 1892, pp. 461-463, It comprises the species quoted in 

 the various papers by Hidalgo in the ' Journal de Concliylio- 

 logie,' 1887, pp. 36, 37-58,93-192, 1888, pp. 30-97, and 

 in Dohrn^s " Beitrag zur Conchylienfauna des philippinischeu 

 Insel Palawan " f. 



Including the new Lagochilus similis here described tour- 

 teen species of land-moUusks have now been recorded from 

 Balabac, The Amphidromus qnadrasi^ although appearing 

 in Mr. Cooke's list, was not previously known from Balabac, 

 but only from a small adjacent island called " Isla de Can- 

 daranianes " {Hidalgo). Anotlier species from this island 

 quoted by Hidalgo % and not in Mr. Cooke's list of tiie 

 Balabac shells is Gorasia zamhoangce, Hombron and 

 Jacquinot.
