 Anim. sans vert. no. 67. Venus Beudanti, Payr. Cat. pi. i. 

 f. 32. 



T. test^ ovali-oblonga, concentrice minutissime striata, sub- 

 compressfi, utrinque acuminata, rufa, versus umbones violascente, 

 albo-biradiata ; latere antico breviusculo ; lunula indistincta. 



Hatter, more acuminated (particularly at the hinder end), and 

 much more finely striated, than T.Jloridella. The colour is a de- 

 licate pinkish-fawn, minutely spotted, and gradually becoming 

 purple towards the apex, from which radiate two white lines, 

 dividing the surface into three parts. 



Probably European. 



36. Tapes acuminata (pi. cxlix. f. 105), Sowerhy,jun. 



T. testa T.florideUce simili, sed laevigata; fulva, maculis fuscis 

 punctata et radiata. 



Exactly like 7'. /onV/tf/<?a in form, but quite smooth. — Obs. 

 Since sending this to the composer I have, on further considera- 

 tion, concluded that this is but the young of T.floridella, which, 

 like that of T. virginea and T. geograpldca, is always smooth. 



37. Tapes Hanleyi (pi. cxlix. f. 102, 103), Sowerby,jun. 



T. testa parva, subtrigona, concentrice striata, purpurascente- 

 albo et macuhs fuscis biradiata, intiis purpurea, utrinque subacu- 

 minata, postice subelongata ; lunula impressa ; dente cardinali an- 

 tico magno. 



A small purplish shell, with very fine concentric striee, radiated 

 with bands of white, interrupted by little linear spots on each side. 

 The upper margins are sloping and the terminations rather 

 pointed ; the hinder side is about twice as long as the front. 



Eio Janeiro. The specimen is in Mr. Hanley^s collection.

 trali post medium arcuato. 



Oval, inclining to cordate, closely and evenly grooved ; sides 

 sloping and both terminations rather pointed. The ventral edge 

 has a peculiar swell behind the centre, by which this species may
