Helix Jacksoniensis. Hel. testd depressd, pallida brunned, po- 

 litd, concentrice substriatd ; spird convexd ; anfractibus planis, 

 ultimo rotundato, depresso ; aperturd lunatd ; fauce albidd ; labia 

 externa tenui. 



Axis 3, diam. 3+ lln. 



Hab. in Nova HoUandia, prope Port Jackson. 



The shell resembles Hel. nitida in form, but is imperforate. 



To Mr. Cunningham Mr. Gray was also indebted for three species 

 discovered by him in Phillip's Island, a small island about 5 miles 

 South of Norfolk Island. These he characterized as follows : 



Helix Campbellii. Hel. testd conicd, subglobosd, depressius- 

 culd, imperforata , subrugosd, rugis transversis densis, striisque 

 spiruUbus indistinctis ; pallide brunned, fascia lata subposticd 

 pallida ; spird conicd, convexd ; anfractibus platiiusculis , ultimo 

 carind mediand indistinctd, antice leEvi ; peristomate tenui, acuta, 

 juxta axin subincrassato , albo. 



Axis 5-J-, diam. 8-J- lin. 



Hab. in Insula Phillip Maris Pacifici. 



Helix Phillipii. Hel. testd subglobosd, depressd, imperforata, 

 pallide corned, pellucidd, maculis viridibus sparsis irregularibus ; 

 transversim subdistanter rugosd ; spira convexd ; anfractibus pla- 

 niusculis, ultimo pnrum ventricosa, rotundato, fascia posticd sv.b- 

 mediand angustd ulbd ; aperturd semilunatd ; labio tenui, supra 

 axin subincrassato, albo. 



Axis 5, diam. 8 lin. 



Hab. in Insula Phillip. 



Jun. spird planiusculd, anfractu ultimo subcarinato. 



This species is allied to the former in the shape of the mouth and 

 structure of the lip ; but the whorls are angular in the young state 

 only, as in most of the Helices of Lamarck. 



Carocolla Stoddartii. Car. testd conico-subglobosd, depressi- 

 usculd, tenuissime rugosd, brunned pallide fasciatd vel flaves- 

 ccntefasciis saturatioribus, imperforatd ; spird conicd, convexd; 

 anfractibus planiusculis, ultimo indistincte in medio carinato ; 

 peristomate tenui, juxta axin subincrassato, acuta. 



Axis 4, diam. 7 lin. 



Var. 1 . Testd saturate brunned, fascia prope suturam latiusculd. 



Var. 2. Testd supra brunned, infra favescente, fascid pone carinam 

 lata brunned. 



Var. 3. Testd pallide flavd, fascid ante carinam latd brunned. 



Var. 4. Testd pallidr fiavd supra brunneo subnebulosd. 



Hub. in Insula Phillip. 



The remaining species were described from specimens in Mr. 

 Gray's own collection ; they were characterized as foUows :
