crisso Jlavicante ; rostro superiore nigro, inferior e flavicanti- 

 albo : pedibus fuscis. 



Long, tota 8'0, alse 3*4, caudse 2*5, tarsi 0*85. 



The form is easily distinguishable from Myiadestes by its longer, 

 stronger, and thicker bill, the larger size of the spurious primary, 

 the relatively longer second primary, and particularly by the shorter, 

 broader, and more rounded tail. 



For the Ptilogonys nitens of Swainson, erroneously referred to 

 this genus by Baird, I propose the generic name Phainopepla 

 (paeivds, nitidus, et 7re7r\os, vestis). 



4. Description of a New Cyrena and Bulla. By Sylvanus 

 Hanley, F.L.S., &c. 



Cyrena cochinensis. C. testa cordata, crassa, valde ince- 

 quilate obliqua, ventricosa seu tumida, epidermide nitente, 

 nigro-fuscescente vestita, sulcis remotiusculis antice exarata, 

 postice magis minusve laevigata : extremitate lateris antici per- 

 brevis rotundata ; lateris postici attenuati productique, in 

 adultis obtusa, in junioribus rotundato-acuminata : margine 

 ventrali arcuato antice valde, postice parum acclivi : natibus 

 obliquis, erosis, prominentibus : lunula nulla, loco ejus autem 

 sulcorum experte : area dorsali postica lata, retusa : superficie \ 

 interna alba, margine cardinali violaceo sparso, concavitate } 

 nonnunquam rubescente, sinu palliari vix ullo : dentibus pri- 

 mariis vix emarginatis ; lateralibus haud manifeste striatis, 

 sub lente autem minutissime corrugato-granosis, antico brevi et *:^ 

 valde approximato, postico elongato et remotiore. \

A few individuals of this strongly-marked species were sent, in 

 company with some Veloritce, from the Malabar coast, by my 

 collector, Mr. "Winkle. In external aspect the shell somewhat re- 

 sembles the V. cyprinoides ; but probably Balissa would be selected 

 for its reception by those who differ from me in subdividing the 

 very natural group Cyrena : the very minute shagreening of its 

 lateral teeth, however, scarcely answers the definition of that sub- 

 genus. The primary teeth are somewhat peculiar, and have a 

 tendency to shelve outwards ; the hinder and central ones are not 

 strictly bifid, but exhibit a kind of shallow sublateral grooving ; the 

 front one in the right valve is very short, and simply pyramidal. 

 The beaks are probably acute when young ; the surface below the 

 epidermis is reddish purple. 



Bulla (Cylichna) carpenteri. B. testa minuta, cylindrica, 

 brevi, medio subretusa, alba superne et inferne rotundata vix- 

 que attenuata, liris gracilibus confertis longitudinalibus, et 

 striis confertioribus exilissimis spiralibus, undique sculpta : 

 umbilico apicali magno, anfractibus spires manifestis ; labio
