COSTELLAHIA. 173 



going description indicates snch close aflinity with T. Siilueyrsiti, 

 however, that I think it wouhl have been more prndent not 

 to separate it. T. fusoo-apicata (fig. 460) and T. Gofoensis^ E. A. 

 Smith, (fig. 4()1), are both s^monymons, varying onl}' slightly in 

 sculpture and marking from the type. 



T. CRUENTATA, (Chemn.) Reeve. PI. 51, figs. 462-406, 468, 469; 



n. 58, fig. 686. 



Ches^inut or chocolate-brown, with a superior narrow white 



band, and occasionally an inferior one. Sometimes lighter 



colored between the band and the suture. Length, '75-1 inch. 



Indian Ocean, Philippmes, Polynesia., 

 A very variable species, which has received a number of names. 



Var, PROXiMA, Nevill. Figs. 464-466, 468. 



The usual Polynesian form ; when one-banded it has been 

 called var. Sandvichensis, Nevill. 2\ e.rarata, A. Ad. (fig. 465), 

 T. ligata, A. Ad. (fig. 466), and T. vibex, A. Ad. (PI. 58, fig. 

 686) are synonjans. I think that T. larva ^ Lam. (fig. 46 8 j may 

 also be placed here. 



Yar. ARMiLLATA, Rcevc. Fig. 467. 



A narrow form, Avith spire drawn out, tjqjicall}^ very different 

 from crueniafa^ var. proxima, but connected with it by Poly- 

 nesian specimens before me. 



T. ScHOMBURGKii, Angas. PL 51, fig. 470. 



Livid brown, with a broad, pale, suffused band on each whorl, 

 and four narrow, dark-brown lines encircling the last whorl, one 

 above and three below the band. Length, 10 mill. 



So. Australia. 



I am not acquainted with this species. 



T. BucGiNoiDEA, Sowb. PL 51, fig. 467. 



Yellowish white, with a white central band bordered Avith 



chestnut on each side. Length, 4 inches. 



Habitat laiknoicn. 

 T. Rawsoni, Morch. 



An unfigured species, from the West Indies, is said to resemble 

 T. cruentata.
