1873.] NEW SPECIES OF ACHATINELLINJE. 79 



crementi lineis leviter striata, dilute brunnea, saturatius vel cinereo 

 strigata ; regio umbilicalis scepe castanea ; apex albus ; spira 

 concaviuscula ; anfract. 6, primi 4 planiusculi, cceteri convexi ; 

 sutura saturate castaneo distincte marginata ; apertura intus 

 albida ; perist. fuscescens, intus incrassatum ; plica columellaris 

 valida, rubescens. 



Long. 17 mill., diam. llg. 



Habitat. Sandwich Islands. 



In form this species agrees very fairly with some varieties of lugu- 

 bris, Chem. ; but it has a shorter spire and blunter apex than the 

 usual form of that species. The coloration is of a different character. 



Apex leucorrhaphe, Gk. (Plate X. fig. 2.) 



Testa dextrorsa, breviter ovato-conica, incrementi lineis (haud spi- 

 ralibus) striata, grisea, strigis saturate cinereis irregulariter in- 

 terrupts, lineisque spiralibus paucis albis indistinctis ornata ; 

 sutura late niveo marginata ; anfract. 6|, apex nigrescens, primi 

 4 albi, subplani, cceteri convexi; apertura parva, subauriformis, 

 alba; perist. leviter dilatatum intusque incrassatum ; plica colu- 

 mellaris magna, rosea. 

 Long. 19 mill., diam. 12. 



Var. Testa ovato-conica, griseo saturate cinereoque regulariter stri- 

 gata ; spira recte conica. 

 Station. This species is arboreal. 



Habitat. Kalaikoa, on the island of Oahu. Waimea? a variety, 

 with spire regularly conical, is reported to have been found in 

 Waimea. 



Affinities. It is allied, though not very intimately, to A. apicatus, 

 Nwc. 



Remarks. No sinistral form of this species has been found. The 

 specimen figured is from Kalaikoa. 



Apex lilacetjs, Gk. (Plate X. fig. 4.) 



Testa dextrorsa, globoso-conica, nitida, incrementi lineis (haud spi- 

 ralibus) striata, lilaceo-cervina, albido strigata ; sutura dilute 

 marginata; anfract. 6, primi 3 subplani, albi, cceteri convexi; 

 anfract. ult. medio interdum obscure obtusatim angulatus ; apertura 

 albida ; perist. dilute roseo-fuscum, paululum dilatatum, intus in- 

 crassatum ; plica columellaris valida, pallide rosea. 

 Long. 21 mill., diam. 12|. 

 Station. On trees. 



Habitat. The metropolis of the species is Ahonui, on Oahu. It 

 is also abundant in Kalaikoa, but becomes very rare in Wahiawa, 

 Helemano, and Kawailoa. 



Affinities. It is readily distinguished from A. apicatus, Nwc, by 

 the colour of the apex, which is chestnut in that species, but white 

 in this. 



Remarks. Sinistral specimens are very rare. The specimen figured 

 is from Kalaikoa.
