Numerous speciuiens vvere exhibited from Mr. Cuming's coUec-

 tions of several New Species of Cahjplrceida." 



The new species described in this paper are distribuled and cliarac- 

 terized as foUovvs : 



Subgenus Calyptr^ea. 

 Testą subconica, subacuminata, cyathi basi udhaerente, lateribus 

 liberis. 



a. Cyalho integro. 

 Calyptr.ea rudis. Cul. testdfuscd, nubdepressd, suborbiculari, ra- 

 diatim corrugatd, limbo crenato ; cyatho conceritrice lineato,alb'ido, 

 irregulariter subcirculuri ; epidermide subfuscd : diam. 2 poli. 

 circiter, alt. -^. 

 Hab. ad Panamam et Real Liejos. 



This species, whose white onyx-likecup, adhering only by its base, 

 shows to great advantage againsl the ruddy brown which is the ge- 

 neral colour of the inside of the protecting shell, was found under 

 stones. The young sheils are the flattest and most regular in form, but 

 their inside is generallv of a dirtv white, dimlv spotted withbrown. —

/3. Cyatho Iiemiconico, longiludinaliter ąuasi diviso. (Calyplrsea, Less.) 

 Calypth^a CORRUGATA. Cul. tesld subalbidd , suborbiculuri, subde- 

 pressd, corrugatd; intūs uitente ; cyatho concentrice Uneato, pro- 

 dueto ; epidermide fuscd : diam. \į^ poli. circ, alt. -i\. 

 Hab. in America Centrali. (Guacomayo.) 

 Found under stones at a depth of fourteen fathoms. — W. J. B. 



CALYPTRiEA VARIA. Cūl. testd albidd, suborbiculari, crassiusculd, 

 Longiludinaliter creberrime striatd ; cyatho concentrice Uneato, 

 crassiusculo, producto : diam. ]į, alt. max. i-, alt. min. 4 poli. 

 Hab. in Oceano Pacifico. (Lord Hood's Island, the Gallapagos, 

 and the Island of Muerte in the Bay of Guayaquil.) 



This is u very variable species allied to Cal. eąuestris, and taking 

 almost every shape which a Calyptrcea can assume. It differs in 

 thickness acoording to localiiies and circurastances. — W. J. B. 



CALYPTRiEA CKPACKA. Cal, testd albd, suborbiculari, subconcavd, 



tenui, diaphand, striis numerosis subcorrugatd ; intiis uitente ; 



cyathi ierminationibus lanceolatis : long. 1-rVj i^'f- ' ž. uit. i poli. 



Hab. in sinu Guayaąuil. (Island of Muerte.) 



This was dredged up, adhering to dead sheils, from sandy mud, at 



a depth of eleven fathoms. Besides other differences, the terminat- 



ing points of the divided cyathus are much more lanceolate than they 



are in Cal. varia. — VV. J, 13. 



Calyptrcea cornea. Cal. lesta suborbiculari, complanatd, albidd, 

 subdiaphand, concentrice lineatd et radiaiiin striatd į intūs ni' 

 tente : diam. į, alt. -^ poli. 



Hab. ad Aricam Peruviae,
