1891.] LAND-SHELLS FROM BORNEO. 53 



Nanina (Macrochlamys) jueunda, v. Martens, Preuss. Exped. 

 Ost-Asien, Landschneck. p. 40, t, sii. fig. 7 (1867). 



The specimen figured measures: maj. diam. 19*0, min. 18*5; 

 alt. axis 9*0 millira. 



Var. nana from Dr. Hungerford's collection. This is a MS. name 

 of Mr. Geoffrey Nevill's, and appears in his copy of the ' Hand-list * 

 as given to two specimens sent to the Indian Museum, Calcutta, as 

 a variety of jueunda. The exact locality is not quoted. 



Everettia hyalina. 



Nanina hyalina, v. Martens, Monatsber. Akad. Berlin, 1864, 

 p. 266 ; id. Preuss. Exped. Ost-Asien, Landschneck. p. 241, t. xii. 

 fig. 5 (1867). 



Helix {Macrochlamys) hyalina, Pfeifi'. Monogr. Helic. v. p. 99 

 (1868). 



Size : maj. diam. 22*5, min. 20"25 ; ait. axis 10*75 millim. 



Von Martens describes the animal as black-grey, of a slender 

 form ; tentacles and neck black, v?ith a white central line on the 

 latter ; mantle reflected ; jaw with a middle projection. In many 

 species of Macrochlamys similar dark and white varieties occur. 

 This species occurred in a disused gold-mine at Kapuas-Strom, in 

 Upper Pontianak, West Borneo. 



Everettia aglaia. 



Helix aglaia, Pfeiff. P.Z.S. 1854, p. 289 ; id. Monogr. Helic. 

 iv. p. 46 (1859), et v. p. 103(1868); Reeve, Conch. Icon, pl.cxcii. 

 fig. 1396 (1854). 



Nanina {Macrochlamys) aglaia, v. Martens, Preuss. Exped. Ost- 

 Asien, Landschneck. p. 242, t. xii. fig. 13 (1867). 



Macrochlamys aglaja, var. emarginata, Nevill. 



Two specimens, Borneo {Sower by, ex coll. Lombe Taylor). In 

 this species the suture is not " linea rufescenfe marginata," Nevill, 

 MS., Hand-1. Ind. Mus. 



There is a fine series of these shells in the collection, some 85 

 specimens, and I have examined those in the British Museum. On 

 ray arranging them by localities in juxtaposition, it was at once 

 apparent that those from the Niah Hills, 15 in number, and 2 from 

 Kina Balu were alike and separable from all the rest. These last are 

 Everettia subconsul of Mr. Edgar Smith, Ann. Mag. Nat. Hist., Aug. 

 1887, p. 132, from North Borneo (/. Whitehead), with which I have 

 compared them. They may be known by the less number of whorls, 

 i. e. not being so closely wound, and those from the Niah Hills 

 are very ruddy in colour and flatter on spire (var. depressa, Plate 

 III. fig. 2). 



The remainder are from the following localities : — 



No. 1. Trusan, 12. 



No. 2. Labuan, 82 ; all range from 15 mm. in maj. diam. 



No. 3. Tiga Island, 1 ; same as No. 2.
