Terebra. JBruguibres. 



128. Terebra robusta, Hinds, Proceed. Zool. Soc. 1843, p. 149. Testa turrito-subulata, 

 solida, ponderosa, albida, flamraeis longitudinalibus interrupte picta ; anfractibus inferioribus 

 rotundatis, indivisis, lsevigatis, superioribus versus extremitatem spiise subplanulatis, unicinguliferis, 

 longitrorsum plicatis ; anfractu ultimo rotundato, triseriatim picto, ad basin coarctato; apertura 

 elongata ; columella arcuata, subcallosa ; epidermide luteofusca ; operculo parvo, crasso. 



Tnhab. West coast of America, between 8° 57' and 21° 32' north latitude ; 

 namely, at Panama, Gnlf of Nicoya, Gulf of Papagayo, and San Bias. In from 

 four to eighteen fathoms, sandy mud. 



129. Terebra alveolata, Hinds, 1. c. p. 151. Testa turrito-subulata, attenuate acuminata, 

 nitida, fusca; anfractibus subplanulatis, superne cingulo tuberculato cinctis, infra plico-costatis, 

 interstitiis striatis ; cingulo et anfractu ultimo albo fasciato, maculis quadratis rufis articulato. 



Inhab. Straits of Malacca ; in seventeen fathoms, among mud. 



The description is drawn up from a somewhat young specimen, and the 

 mouth and last whorl have not yet attained their full development. The character 

 of the shell is, however, very conspicuous. In this genus the last whorl will be 

 found very frequently to offer decided features, and becomes a valuable aid in the 

 diagnosis. 



130. Terebra pulchra, Hinds, 1. c. p. 151. Testa turrita, conico-subulata, acuminata, nitida, 

 pallida ; anfractibus subplanulatis, longitrorsum recte plico-costatis, superne linea impressa. cinctis, 

 interstitiis laevigatis ; anfractu ultimo pallide lineato. 



Inhab. Marquesas. In seven fathoms. 



Perhaps more nearly resembling T. plicata than any other species, from 

 which, with a little care, the description will suffice to distinguish it. 



131. Terebra nitida, Hinds, 1. c. p. 152. Testa obeso-subulatS., acuminata, pallide plum- 

 bea, polita; anfractibus subplanulatis, recte plico-costatis, superne interstitiis linea punctata cinctis, 

 ultimo parvo subattenuato, unicolore, plicis evanidis ; labiointerno producto ; labro antice subsinuo<o. 



Inhab. Marquesas. In seven fathoms, sandy mud. 



An excellent diagnostic character exists in this species, in the circumstance 

 that the girdling line which traverses the upper part of each whorl does not cross 

 the ribs, but is confined to the interstices. 



132. Terebra varicosa, Hinds, 1. c. p. 152. Testa elongate conico-subulata, acuminata, nitida ; 

 anfractibus subplanulatis, plico-costatis, superne cingulo tuberculato contractato cinctis; costis
