128. Teieoeis (Ijsro) excelsioe, sp. n. (PI. 10. fig. 5.) 



T. testa producta, multum attenuata, angusta, brunnea, bic 

 ilHc rufo-maculata ; anfractibus quinque- vel sex-et-vigiati, 

 tornatis, apud suturas elevatis, transversim arete tricarinatis, 

 laevibus ; carina infra, juxta suturas, minore, duabus alteris magis 

 conspicuis, interstitia interv^enieute plaaata, ultimo aufractii 

 quadricarinato, carina bina ad peripberiam addita ; apertura 

 rotunda, parva, canali breviter reourvirostri, in uno specimine 

 pone aperturam ipsam clausa. Long. 30, lat. 5 (sp. maj.) mm. 



Pour or five, mostly imperfect, examples. The form is much 

 acuminate and attenuate, narrow ; colour light brown, here and 

 there indistinctly flecked with rufous spotting ; whorls 25 or 2Q, 

 toruate, smooth, elevated at the sutures, closely thrice-keeled 

 transversely, the keel just below the sutures is smaller and less 

 conspicuous than the two lower, the last whorl is four-keeled, 

 there being two on the periphery ; the aperture is roundish, small; 

 in one (the most perfect) specimen the recurved and beaked 

 canal is closed with shelly matter behind the aperture. 



The only species to which, in size, this very conspicuous 

 Triforis could be referred is T. gigas, Hinds, also occurring in 

 the same localities. The sculpture, as seen by the above 

 description, is however totally diff"erent, being smooth, with no 

 interstitial pitting or gemmuled ribs of any kind. Owing to 

 no one specimen being in a state of absolute perfection, we 

 liave been compelled to estimate the number of whorls and the 

 dimensions generally with the aid of two or more examples, each 

 complete in some one particular.
