2. KAUTiLOiDES, f. 104, 105, Lessoii. — G. dilatatce similis, 

 sed profunde concava ; spira magis inflata et contorta. — The 

 habit of this Crepidula is to eoil its shell over others of the 

 same species. Groups of these limpets are found thus with 

 the shells deep and curved. 



3. roLiACEA, f. 103, 106, 107, Broderip. — Subdepressa, 

 lateraliter expansa, alba, intus fasciatim aureo et castaneo 

 fasciata, extus rugose plicata, margine crenato, apice parvo, 

 terminali, septo trigone, curvo, prominente lobato. — Of the 

 same general form as C. dilatata, but wrinkled half- 

 divergentlj, with crenulated margin. The interior is prettily 

 flashed with orange and chestnut. 



4. ONYX, f. 112, Sowerby. — Ovato-oblonga, castanea, lineis 

 rubris radiata fulvo marginata ; apice uncinato terminali, 

 septo late albo rectiusculo ; margine undulatim sinuato. — 

 The original specimen, described in the ' Grenera of Shells,' 

 was overgrown and covered on the outside with extraneous 

 matter, but the natural colour appears to be mahogany, with 

 reddish lines showing at the inner margin. 



5. FORNiCATA, f. 118, 123, Linnceus. — Ovato-oblonga, 

 carnea, punctis minutis rubris adspersa, margine rubro 

 lineato (variat subpurpureo), septo lato elongate recto. — Sus- 

 ceptible of many variations in form and colouring, but 

 mostly sprinkled with the little red dots that have given to 

 one variety the name of C. arenata, Broderip. 



6. EXCAVATA, f. 119, Broderip. — Lsevis, straminea, oblonga 

 irregulariter ovata, lateraliter compressa ; intus fasciis lividis 

 picta ; apice producto uncinato terminali sejito lato, margine 

 recto. — The specimens hitherto found have been bent up at 

 the sides in a peculiar manner. The general colour is a kind 

 of straw, with dark radiating flashes within. 



7. POECELLANA, f. 120, 121, 122, iwrna'tts.— Ovata sub- 

 expansa depressa partim fusco-livida castaneo variegata, 

 margine intus maculate ; apice peculiariter producto mamil- 

 lato ; septo lato brevi, margine leviter arcuato. — The spots 

 with suffused edges, showing strongly on the inner margin, 

 and the peculiarly mamillated and produced darkly coloured 

 apex, are the characteristics of this species. Var. immersa^ 

 f. 122, has evidently been figm-ed from a beach-rolled 

 specimen.
