Helix Jacksoniknsis. Hel. testd depressd, pallidi brunned, po- 

 litd, concentrice substriatd ; spird convexd ; anfractibus planis, 

 ultimo rotundato, depresso ; aperturd lunatd į fauce albidd ; labio 

 externo tenui. 



Axis 3, diam. 34- lin. 



Hab. in Nova Hollandla, prope Port Jackson. 



The shell resembles Hel. nitida in fonn, 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 follo^vs : 



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

 culd, imperforata, subrugosd, rugis transversis densis, striisąue 

 spirulibus iiidistinctis ; pallide brunned, fascid latd subposticd 

 pallidd ; spird conicd, convexd ; anfractibus plahiusculis, ultimo 

 carind mediand indistinctd, antice Icevi ; peristomate tenui, acuto, 

 juxta axin subincrassato , albo. 



Axis 5-į-, diam. 84- lin. 



Hab. in Insula Phillip Maris Pacifici. 



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

 pallide corned, pdlucidd, maculis viridibus sparsis irregularibus ; 

 transversim subdistanter rugosd ; spira convexd; anfractibus pla- 

 niusculis, ultimo parum ventricoso, rotundato, fascid posticd sv.b- 

 mediand angustd albd ; aperturd semilunatd ; labio tenui, supra 

 axin subincrassato, albo. 



Axis o, diam. 8 lin. 



Hab. in Insula Phillip. 



Jun. spird planiusaild, anfractu ultimo subcarinato. 



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

 structure of the lip; but the M'horls are angular in the young stata 

 only, as in most of the Helices of Lamarck. 



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

 usculd, tenuissime rugosd, brunned pallide fasciatd vel flaves- 

 cente fasciis saturatioribus, imperforatd ; spird conicd, convexd; 

 anfractibus planiusculis , ultimo indistincte in medio carinato ; 

 peristomate tenui, juxta axin subincrassato, acuto. 



Axis 4, diam. 7 lin. 



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



Var. 2. Testd supra brunned, inf ra flavescente, fascid pone carinam 

 latd brunned. 



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



Var. 4. Testd pallid'r favd supra brunneo subnebulosd. 



Hab. in Insula Phillip. 



The remaining species were described from specimens in Mr. 

 Gray's o\vn collection ; they were characterized as follows :
