Dentalia by some called pinpaches because pinmeat thereof is taken out with a pinne or needle.[83] [83] Mussels and Cockles are very abundant all along the shallow shores of North-west Norfolk, as well as Clams, _Mya arenaria_. "Scallops of the lesser sort" are probably _Pecten opercularius_ and _P. varius_. The Whelk, _Buccinum undatum_, is also very numerous, and forms the staple of a considerable industry at Sheringham; the lesser, or Dog-Whelk, _Nassa reticulata_, as well as _Purpura lapillus_ and several sorts of Trochus, are commonly met with. The genus Nerita was a very comprehensive one in Browne's time, and included many species of Littorina, of which the well-known Periwinkle, _L. littorea_, is the most numerous here. No true Nerita is now recognised as British, although in the warmer seas the genus is a very numerous one. The most common Tellina here is _T. tenuis_, _Lepades patellæ_ are of course the common Limpet (_Patella vulgata_), and of the Solen, or Razor Shell, which Gwyn Jeffreys says in the time of Aldrovandus was called by the Venetians "cappa longa," we have two species found on the sandy portions of the coast. Here some confusion exists in the MS., after the words, "the shell thereof dentalia," the note ends abruptly, and is followed by an interpolation which seems quite irrelevant, as Dentalia have surely never been called "Pin-patches" (the vernacular name for _Littorina littorea_), nor is it probable that, like that common univalve, they were ever taken out of their shells with a pin or needle. _Dentalia_ are mentioned on two other occasions as of doubtful occurrence and _Dentalium entalis_ has slight claim to be a native of Norfolk; the only recorded specimen I know of was picked up in 1890 by Mr. Mayfield, from the drift on the beach between Wells and Holkham. Cancellus Turbinum et neritis[84] Barnard the Hermite of Rondeletius a kind of crab or astacus liuing in a forsaken wilk or nerites. [84] Hermit Crabs are here referred to, the larger, _Pagurus bernhardus_, found very frequently inhabiting the shells of the Whelk, and a smaller species which takes up its abode in those of a _Trochus_. echinus echinometrites[85] sea hedghogge whose neat shells are co[=m]on on the shoare the fish aliue often taken [with _crossed out_] by the dragges among the oysters. [85] Dead _Echini_ are very common on the sea-shore, and many living ones are dredged by the shrimpers. _Echinus sphæra_ is the most common on the Norfolk coast; _E. miliaris_, a small species, is also very abundant about Cromer. [This and the next paragraph on fol. 33 _verso_.] Balani[86] a smaller sort of vniualue growing co[=m]only in clusters. the smaller kinds thereof to bee found oftimes upon oysters wilks & lobsters.
