slightly impressed ; aperture ovate; lip acute, thickened within ; 
columella white, short, broad and abruptly twisted; colour light 
chestnut, with darker longitudinal stripes, green at the base ; a white 
sutural band for the last 24 whorls, and a brown band on the suture 
above. 
But a solitary specimen of this species has been obtained. Its cha- 
racters are, however, sufficiently striking to warrant us in giving it a 
place as a distinct species. 
61. ACHATINELLA GERMANA (PI. XXIV. fig. 61). A. testa dex- 
trorsa, ovato-conica; anfractibus 6, plano-convevis ; apertura 
ovata; labro acuto, intus incrassato; columella brevi, tubercu- 
lari, fusca; colore castaneo cum lineis delicatis, obsoletis, trans- 
versis, obscurioribus, vitta alba suturam ultimam transeunte et 
anfr. ventralem medio secante; fascia lata in apertura evanes- 
cente, columellam circumdante. 
Long. = lat. 5 poll. 
Hab. Makawao, Mani. 
Shell dextral, ovately conical; whorls 6, flatly convex; aperture 
ovate ; lip acute, thickened within; columella brown, short and tu- 
bercular ; colour chestnut, with fine obsolete darker transverse lines ; 
a white band traverses the last sutural whorl and cuts the body whorl 
centrally ; around the columella is a broad white band, losing itself 
in the aperture. 
Closely resembles the A. solitaria, and but for the widely distant 
localities, might be taken for a variety of the same species. The mark- 
ings and columellze are however quite distinct. 
62. ACHATINELLA FLAVESCENS (Pl. XXIV. fig. 62). A. testa 
dextrorsa, conica; anfractibus 6, subrotundis ; sutura simplici, 
bene impressa; striis numerosis longitudinalibus, et bene expres- 
sis; apertura semiovali; labro simplici; columella brevi, dente 
obliquo, plicato munita ; colore teste externe uniusmodi subflavo, 
interne albido vel subroseo. 
Long. =; lat. 2 poll. 
Hab. Hawaii. 
Shell dextral, conical; whorls 6, slightly rounded ; suture simple, 
well-impressed ; strize numerous, longitudinal and well-developed ; 
aperture semiovate; lip simple; columella short, with an oblique 
plaited tooth; colour of shell externally of a uniform light reddish 
yellow, internally white or pale rose. 
This species belongs to a group, at the head of which stands 4. ru- 
bens of Gould. Its specific character is sufficiently marked. It is 
one of three species thus far obtained on the large island of Hawaii. 
63. ACHATINELLA Hetena (PI. XXIV. fig. 63). A. testa ovato- 
conica ; anfractibus 5, ventricosis; sutura profunda; apertura 
ovata; columella subcallosa; striis minute decussatis ; colore rufo 
alternante cum lineis ziczac albis, longitudinalibus, latis, totam
