The Ualiotidtt, which are all marine and littoral, bcin^ without 

 npercula, adhere, like the Patella, by applying tlii-ir undrr part* to 

 the aurfaoe of the rock*. They are generally found near the water 1 * 

 edge, and, according to Lamarck, go during the fine summer iiighU to 

 feed on the herbage which grows near the shore. 



As an article of food this genus is by no means to be despised. U',- 

 hare eaten Hcdtutu tubtrcuJala, and when served by a good cook it is 

 tender and sapid. The large fleshy foot, if not properly managed, U 

 apt to be tough. The people of Guernsey and Jersey onuiuient 

 houses with the shells of this species, disposing them frequently in 

 quincunx order, and placing them so that their bright interior m:iy 

 catch the rays of the sun. We have often thought that some ol'tl 

 and splendid intertropical species, whose exterior, uft. r n-muviu^ tuo 

 outer coat, take a polish almost equalling the uutural brilliancy of tlu> 

 inside, might be converted into diiiheg for holding fruit : if mounted 

 with good taste, their indescribable iridescence would materially add 

 to the richness of an elegant table. As it U, the shells of U. luliercu- 

 tola are extensively used for making mother-of-pearl ornaments, espe- 

 cially in ornamenting papier machtf articles. For this purpose great 

 quantities are taken to Birmingham. 



B. Species whose disc, besides the series of holes, is raised by a Urge 

 parallel rib, hollowed interiorly, and whose anterior border is 

 more or less irregular. 



Padolliu (De Montfort). M. Do Blainville refers to I/aliola canalic- 

 lala (Lamarck), as the example. The figure in Kuorr, referred to by 

 Lamarck, in red externally, and has the elevated rib ; but the shape 

 of the shell U longer than that of Padollui icalarit (Leach), and of 

 other PadoUi which we have Keen. The specimen recordi.l l.y Mr. 

 Gray in the Appendix to the 'Narrative of a Survey of the int<-r- 

 troptcal and nestern Coaste of Australia, performed betwe< 

 years 1818 and 1822, by Captain Philip Parker King, H.N., 1 

 *c..' voL ii., and which Mr. Gray notices as the largest be ever saw, 

 measured 34 by 2J inches. We have seen the shell, and never saw 

 *n large a specimen. Dr. Gray records it as Padollia rubicundtu of 

 De Montfort, with the synonyms of Padollui tcalarii, Leach, and 

 llaluttit tricoftalii, Lamarck. 



Padollm r.4r>i,,irfiu (!). 



Lamarck, on the authority of M. Leschenault, says that his // 

 tncadalit inhabits the seas of Java. The fine specimen brou: 

 Kngland by Captain King was found upon Rottnest Island, 

 west coast of Australia, and is now in his cabinet. It has only 

 bole*, the anterior ones, open. All, both those which are clo8< - 

 those which are open, are very highly elevated, and so is the curvnl 

 longitudinal rib. The left border externally is very much raised and 

 nodulous, looking at first sight as if it bad another row of holes which 

 had been closed ; but it was evidently always irnperfonite, 



C. Species whose disc is not pierced, but hollowed longitudinally by 



a decurrent canal. 



M. De BUinville gives as an example of his Be. ti.iji <'. //. 

 of Lamarck. It will be clear to the observer that the animal protected 

 by such shells as the two next, must exhibit some differences from 

 Umt of a true llaliotit. 



D. Specie* whose disc is not pierced, and which offer the two gutters 



together, but approximated, so as to leave externally a decurrent 

 rib between them. 



Somalia (Lamarck). Cuvier, who says that the animal of Stomatia 

 U much lees ornamented than that . U of opinion that this 



form connects the Ualioddet with certaiu TVv 



Mr. G. Sowerby ('Genera of Uecent and Fossil Sli.l]*,' Xo. xix.) 

 obeerre* that Lamarck, in his observations upon StomateUa, tclU ux 

 that in respect to their general form those shells appear to be n 

 related to the Stomatia; and that they are principally distiugi. 

 by the transverse ridge and the elevated outer lip of the , 

 Lpon a careful examination however of ten species, Mr. Sowcrby was 

 unable to discover any difference in the outer lip ; and 

 that Lamarck places am- /,,-./, wlii.-h 



has a nodular keel placed exactly in the same position as the trans- 

 Terse ridge, by which the latter characterises tiomaiia ; so th;. 

 Sowerby doe* not find any generic difference whatever, and has tin ru-
