[91] It is difficult to determine the species of marine Annelids referred to by Browne; the Sea Leech is probably _Pontobdella lævis_. The "large wormes" digged for bait, mentioned more than once, are Lug-worms, _Arenicola piscatorum_; the _Vermes in tubulis testacei_ may be tube-worms of the genus Terrebella, or a species of Serpula. Tethya or "Sea dugge" (not "Sea dogs," as Wilkin has it) might very well apply to _Ascidia_ or one of the allied genera. Simple Ascidians, generally known as Sea-squirts, are common littoral forms; the animals figured by Rondeletius under the heading "De Tethyis" (p. 127) are simple Ascidians. The _vesicaria marina_, or "fanago," might well refer to the egg capsules of the common Whelk (_Buccinum undatum_), which are very commonly found in masses on the shore. In his sixth letter to Merrett, Browne mentions two kinds of "fanago," the first which I take to be the egg capsules of the Whelk, resembling the "husk of peas;" the smaller that of "barley when the flower [awn?] is mouldered away," may possibly be the egg capsules of _Purpura lapillus_, or of some species of Natica, which bear a fanciful resemblance to grains of barley. See also Merrett's second letter in Appendix A., in which he describes the Vesicaria found on oyster-shells as resembling flowers of _Hyacinthus botryoides_, which is not a bad description of the form of the egg capsules of _P. lapillus_. vermes marini very large wormes digged a yarde deepe out of the sands at the ebbe for bayt. tis known where they are to bee found by a litle flat ouer them on ye surface of ye sand. as also vermes in tubulis testacei.
