Bab.— Norfolk Island. 



Mr. Suter has recently placed this species in Medyla, on anatomical 

 grounds, and I have followed him. Having examined Morelet's type- 

 specimen, now in the British Museum, I am enabled to state that the 

 suggested identity of these two species is, in my opinion, thoroughly 

 justified, and doubtless Morelet's habitat of " Siam" was an error. 



9. Medyla ijiitatrix, n.sp. PI. XIII, Figs. 1 and 2. 



Testa imperforata, elevato - conoidea, costulis obliquis asperatis 

 regulariter notata, cornea, maculis castaneis picta, apice acutulo, 

 applanato ; anfractus 5£, planulati, ultimus carinatus, basi fere 

 leevis, subimpressus, lineis increment! et spiralibus obscure notata, 

 sutura impressa ; apertura rhomboidalis, margine dextro acuto, 

 columellari incrassato, saepe dente inconspicue, albido, munito. 

 Alt. 55, diam. max. 5 mm. 



Hah. —Norfolk Island, under dead bark and leaves (coll. Brit. Mus.). 



Akin to M. imculpta, Pfr., but much more elevated in proportion 

 to the breadth ; the base also being somewhat impressed and not 

 inflated. Fresh specimens show a few scattered hairs ; one is pure 

 white in colour. 



10. Sitala Macgillivrayi, n.sp. PL XIII, Fig. 3. 



Testa subperforata, trochiformis, sub lente leviter et dense striatula, 

 lineis spiralibus notata, nitidula, fusco - cornea, apice obtusulo ; 

 anfractus 5, piano- convexi, ultimus carinatus, basi subinflatus, sutura 

 bene impressa ; apertura subquadrata, marginibus acutis, columellari 

 subivflexo. Alt. 2, diam. max. 2 - l mm. 



Mai.— Norfolk Island (coll. Brit. Mus.).

Helix Jloaculus, Cox: Proc. Zool. Soc, 1865, p. 695; Journ. de

Hah. — Phillip Island (Cray) ; Norfolk Island (Cox, Turner, coll. 

 Brit. Mus.). 



In my opinion the shell described by Mr. Cox is only a small race 

 of C. Stoddarti ; the shape, size, and colour- markings all seem to be 

 variable. 



12. CnARorA EXAGITANS (Cox). 



Helix exagitans, Cox: Proc. Zool. Soc, 1870, p. 83. 



Hub. — Norfolk Island, found in damp places in the pine forests, 

 under leaves (Brazier); between dead leaves (coll. Brit. Mus.). Both 

 the type a.nd the specimen in the Natural History Museum have been 

 broken.
