Descriptions of Seven New Shells from the Collec- 

 tion OF the Hon. Sir David Barclay, of Port Louis, 

 Mauritius. By Lovell Reeve, F.L.S., F.G.S. 



Sir David Barclay, a gentleman resident at the Mauritius, and 

 long known to conchologists as a zealous collector of shells, having 

 availed himself of the occasion of visiting this country to bring a few 

 of the rarer specimens of his cabinet for comparison, I have, at his 

 request, examined them, and selected the following as being new : — 



1. Strombus TAURUS. Stro7n. testa ovata, crassissima, pari' 

 derosa ; spira exserta, nodoso-tuberculata ; anfractibus trans- 

 vershn striatis et tenidliratis, idtimo superne obtuse angidato 

 et perampliter bi- tri-tubercidato, tubercido obliquo peramplo 

 infra in medio ornato ; columella densissime callosa, superne 

 fere ad apicem appresse dilatata ; apertura subcontracta, labro 

 dense incrassato, tuberculis peramjylis obtusis armato superne 

 bidactylo, dactijlo supremo elongato, curvato ; albida, aurantio- 

 ftisco variegata et sparsim vittata, columella et apertura fauce 

 ridjido-carneo tinctis. 

 Long. 3i poll., lat. 2f poll. 



Hab. Amirante Islands, a group of the Seychelles. 

 This remarkable shell, which Sir David Barclay has for some time 

 past known as an undescribed species, and distinguished in his 

 cabinet by the above name, is curiously intermediate in its generic 

 characters between Strombus and Pterocera. In detail of pattern 

 and sculpture it resembles. S. laciniatus, but there is a large central 

 oblique tubercle on the back, and the lip is thickened into two very 

 large obtuse oblong tubercles, the upper part being produced into 

 two decided Pterocera claws, one of which is prolonged in a curved 

 manner to the extent of an inch and a half. The specimen has 

 rather the appearance of being malformed ; but notwithstanding this 

 seeming irregularity of growth, there is no doubt w'hatever of its 

 being specifically distinct from any hitherto described form. 



2. Cypr.ea Barclayi. Cypr. testa pyriformi-ovata, subumhili- 

 cata ; dorso elevatiuscido, extremitatibus eleganter calloso-pro- 

 ductis, subrostratis ; basi convex a ; dentibus utrinque octo- 

 decim ad novemdecim fortibus tumidiusculis j interstitiis con- 

 spicue sulcatis, ijrofundis ; dentibus exterioribus super Inbi'um 

 decurrentibus, medianis bifdis ; nitente, alba, dorso aurantio- 

 spadiceo undique eximie punctata et lentiginoso, extremitatibus 

 aurantio-spadiceo tinctis. 



Long. 1 poll., lat. |- poll. 



Hab. Island of Diego Garcia, a dependency of ]\Iauritius (taken 

 on a block of coral dredged up from deep water).
