angulaius, antice pernio descendens ; apertura late ei oblique 

 lunata, intuslivido-fuscescens ; peristoma tenue, pallide lilaceum, 

 undique expansum, marginibus remotis, callo tenuissimo nitenie 

 junciis. 



Diam. maj. 30 millim., min. 24, alt. 17. 



Hab. Panaliugoan, south-west of Palawan. 



Much larger than H. tomentosa, more widely umbilicated and of 

 a different form. 



42. Helix (Dokcasia) incauta. (Plate III. fig. 18.) 



Testa subglobosa, tenuis, anguste umbilicata, cornea vel pallide 

 rubescens, epidermide tenui olivacea ituluta, incrementi lineis 

 striata ; spira brevis, conoidea, ad apicem subacuta ; anfractus 

 6, leviter convex iusculi, ultimus ad peripheriam obsolete angu- 

 lati(s, angulo linea subpellucida picto, antice haud descendens ; 

 apertura late lunata, obliqua ; peristoma subincrassatum, 

 lilaceum, margine dextro vix reflexo, columellari dilatato et 

 reflex 0. 

 Diam. maj. 16 millim., min. 14, alt. 14 ; apertura 8 longa, 



7-5 lata. 

 Hab. SaraAvak (Bartlett). 



A single specimen was presented to the British Museum by 

 Mr. E. Bartlett in 1893. It somewhat resembles R. fodiens, 

 Pfeiffer, but is more finely striated and has a more pointed spire. 

 In addition to the fine lines of growth, faint traces of spiral 

 strias are also observable. 



43. Helix (Papuina ?) rufopilosa, Bock. 



Helix {Geotrochus) rufofilosa, Bock, Proc. Zool. Soc. 1881, 

 p. 630, pi. Iv. fig. 4. ■ 



Helix (Satsuma) rufofilosa, PUsbry, Man. Conch, ser. 2, vol. vii. 

 p. 84, pi. iii. fig. 55. 



Hab. Meri, Sarawak (C Hose) ; Paio, Sumatra (Bock). 



The single example collected by Mr. Hose is exactly similar to 

 the tvpes of this species presented to the Museum by Mr. Bock. 

 Is it probable that this species occurs both in Borneo and Sumatra? 

 I am rather inclined to think that Mr. Bock has made a mistake 

 with regard to his locality. This might easily have occurred, as he 

 collected in both islands. 



44. Helix (Plectoteopis) winteeiajsta, Pfeiffer, var. /3. 



Hab. Busau, West Sarawak. 



The specimens from this locality agree with Pfeiffer's var. /3 

 founded on Philippine examples. They are of the same small size, 

 have a more pronounced keel than typical Javan specimens, and 

 the under surface exhibits more distinct concentric striation than 

 the typical form. These striae are even more apparent in the 

 shells from Guimaras. Both Martens * and MoeUendorff ' question
