 Hab. Ceylon. Mus. Cuming. 



An unique specimen of this curious shell is in the museum of Mr. 

 Cuming, aad reminds us in many particulars of the Tellina Gargadia ; 

 but tliat species is neither so narrow nor so greatly ineąuilateral, its 

 obliąue strise do not extend over the posterior portion of the shell, 

 and its hinge is clearly provided \vith t\vo lateral teeth. The elevated 

 flexuous wrinkles radiate down the umbonal slope in three distinct 

 lines. 



Tellina Felix. Tel. testd subovali, solidiusciild, valde incBcuilate- 

 rali, convexiusculd, nitidd, Icevigatd, inius extusque rosed ; margine 

 ventrali vix convexiusculo ; dorsali antice vix declivi, convexo, 

 postice valde declivi ; latere postico brevissimo, obtuse subtruncato, 

 inferne subangulato ; extrsmitate anticd rottindatd ; costd timbonali 

 et flexurd ventrali subobsoletis ; cardine dente laterali magno, 

 approximato, antico. Long. 0'38 ; lat. 0"80 poil. 



Hab. Panama; sandy mud, six to ten fathoms. 



This elegant little shell approximates in form to the British Dona- 

 cina, but difFers as ■well in colouring as in sculpture and teeth. 



Tellina Columbiensis. Tel. testd ellipticd aut oblongo-ellipticd, 



compressiusculd, subtenui, lavigatd, intus extusque albidd, epider- 



mide tenuissimd, fulvo-cinered indutd ; margine ventrali medib 



convexiusculo, ulrinque arcuato ; dorsali utrinque convexo, antice 



paullh, postice satis declivi ; latere antico longiore, rotundato ; 



extreniitate posticd acuminatd ; flexurd subobsoletd ; dcntibus pri- 



mariis minintis, lateralibus nullis. Long. 1*70 ; iat. 3 poli. 



Hab. Monte Christi, West Coiumbia ; sandy mud, tvvelve fathoms. 



Its more compressed valves and minute teeth ■will distinguish it 



from the few species ■vvhich are allied to it in outline. The hinge- 



margin is very short and rather broad . The general shape is that of 



T. Soverbii. 



Tellina Souleyeti. Tel. testd. oblongd, tenuiusculd, convexo- 

 depressd, intus extusque albidd, Icevigatd ; margine ventrali magis 

 minusve convexo ; dorsali antice convexiusculo et subdeclivi, pos- 

 tice subrecto aut subretuso et valde declivi; fleiurd costdque um- 

 bonali distinctis ; ligamento infosso ; natibus acutis ; latere antico 

 longiore, rotundato ; extremitate posticd subrostratd ; dentibus 

 lateralibus nullis. Long. 0'75 ; lat. 1-25 poli. 



Hab. St. Nicholas, Zebu ; sandy mud at low water.
