 plicata ; labio interno product©. 



This Asiatic species very closely resembles the American 

 just described, and furnishes another of those instances of 

 affinity, which, whilst still retaining unquestionable distinct- 

 ness, occur so frequently in the shells of the tropics of the 

 two hemispheres ; and thus, whilst both are enriched by similar 

 forms, these present themselves under slight but constant 

 differences. It also bears considerable resemblance to T. flava, 

 but the characters are quite sufficient to recognize each.

80. T. CANCELLATA. (pi. xUv. f. 80.) Quoy, Voy. de 

 I'Astrolabe, p. 471, t. 36, f. 27, 28. 



Testa subulata, acuminata, fusca, concolore; aufractibus 

 planulatis, superne linea excavato-impressa divisis, plicatis ; 

 plicis numerosis, acutis, subobliquis, interstitiis striatis ; aper- 

 tura utrinque attenuata, atro-fusca; columella antice producta ; 

 breviter canaliculata. 



The characters here are so negative, that it is not easy to 

 seize on any circumstance which language can express to 

 establish its distinctness, whilst this to the eye is unquestion- 

 able. Its uniform colour must not be overlooked, or the 

 absence of banding on the last whorl. The aperture is of a 

 dark brown, and a ridge of similar colour runs from the 

 columella around the base of the last whorl. This species 

 has priority of T. cancellata, Gray, which unfortunately 

 is only known to us from description.

81. T. PULCHRA. (pi. xlv. f. 129.) Hindsy 1. c. p. 151. 



Testa turrita, conico-subulata, acuminata, nitida, pallida ; 

 anfractibus subplanulatis, longitrorsum recte plico-costatis, 

 superne linea impressa cinctis, interstitiis Isevigatis ; anfractu 

 ultimo pallide lineato. 



Perhaps more nearly resembling T. plicata than any other 

 species, from which, with a little care, the description 

 will suffice to distinguish it.
