Species 32. (Fig. 32, Mus. Cuming.) 



Terebra dislocata. Ter. testa conico-subulatd, tur- 

 ritd, cinereo-albd, purpureo-spadiceo fasciatd, versus 

 apicem rufescente-flavd, anfractibus declivi-planatis, 

 longitudinaliter plicato-liratis, liris subarcuatis, inter- 

 stitiis transversim lineari-sulcatis, superne sidco con- 

 spicue divisis, ad marginem tuberculato-nodosis ; colu- 

 mella constrictd et contorto-recurvd. 



The dislocated Terebra. Shell conically subulate, 

 turreted, ash-white, banded with purple-fawn, reddish- 

 yellow towards the apex, whorls slopingly flattened, 

 longitudinally plieately ridged, ridges slightly arched, 

 interstices transversely linearly grooved, conspicuously 

 divided at the upper part by a groove, tubercularly 

 noduled at the margin ; columella constricted and 

 twistedly recurved.

 Terebra Pelitii, Kiener. 



Hab. Southern United States and California. 



The folds and nodules stand out conspicuously white 

 upon a purple-ash ground . 



Species 33. (Fig. a, b, Mus. Cuming.) 



Terebra gemmulata. Ter. testa subulato-turritd, al- 

 bidd, plus minus rufescente-fusco fasciatd, anfractibus 

 concavo-plaii.atis, longitudiualiter plicato-liratis, liris 

 arcuatis, nunc distantibus, nunc coufertis, superne uo- 

 dulatis, anfracluum parte supremd concavo-sulcald, ad 

 marginem nodulatis ; columella tenui costatd, saturate 

 fasciatd. 



The gemmed Terebra. Shell subulately turreted, 

 white, more or less banded with reddish-brown, 

 whorls concavely flattened, longitudinally plieately 

 ridged, ridges arched, sometimes distant, sometimes 

 close-set, noduled at the upper part, upper part of 

 the whorls concavely grooved, noduled at the mar- 

 gin ; columella thinly twisted, darker banded.

 Terebra Patagonica, D'Orbigny. 

 Terebra Chilensis, Deshayes. 



Hab. Patagonia, Chili. 



A careful comparison of the original types of T. Pata- 

 gonica and Chilensis with authentic specimens of M. Kie- 



ner's T. gemmulata leaves no doubt in my mind of their 

 being different states of the same species. M. D'Orbigny's 

 shell, T. Patagonica, — and he had but one, — now in the 

 British Museum, is a large specimen, in bad condition, ar- 

 tificially elaborated in his figure in the Voy. dans l'Ame- 

 rique Meridionale. M. Deshayes' shell, T. Chilensis, — and 

 he has but one, — is a slenderly convoluted form of the 

 species, with the longitudinally plicated ridges rather nu- 

 merous and close-set. 



Species 3-1. (Mus. Cuming.) 



Terebra rudis. Ter. testa subulato-turritd, albidd aid 

 rufescente, apicefavo, anfractibus plants, longitudina- 

 liter plicalis, transversim lineari-sulcatis, cancellatis, 

 superne sulco divisis, margine concentrice nodularis . 

 aperturd parviusculd, columella contortd. 



The rude Terebra. Shell subulately turreted, whitish 

 or reddish, apex yellow, whorls flat, longitudinally 

 plicated, transversely linearly grooved, cancellated, 

 divided round the upper part by a groove, margin 

 concentrically noduled ; aperture rather small, colu- 

 mella twisted.

 Myurella rufo-cinerea, Carpenter. 



Hab. South Carolina ; Dr. Jay. 



It is somewhat doubtful whether this is not a variety of 

 Say's T. dislocata, figured above it. 



Species 35. (Mus. Cuming.) 



Terebra cinerea. Ter. testa acute subulatd, griseo-ci- 

 nered, intus castaneo fasciatd, anfractibus declivi-pla- 

 natis, longitudiualiter tenue undato-striatis, superne 

 minute vel modice creberrime plicalis et interdum pur- 

 pureo maculalis ; aperturd parvd, columella callosd, 

 nitide cuslaued, recta, subtruncatd. 



The ash-coloured Terebra. Shell sharply subulate, 

 greyish-ash, chestnut-banded within, whorls slopingly 

 flattened, longitudinally finely wave-striated, minutely 

 or moderately closely plicated, and s imetimes pur- 

 ple-spotted round the upper part ; aperture small, 

 columella callous, shining-chestnut, straight, some- 

 what truncated.
