 A HISTORY OF SUFFOLK with Uljanin's figure.*' On the basal joint of the first antennae in the male there is in the Lowestoft specimen a seta widened near the base, with the border of this widened part pectinate. In this species the first antennae of the female are ii-jointed. C. fimhriatus, Fischer, which is perhaps the same as C, crassicornis, O.F.M., has 8-jointed first antennae. The Lowestoft specimen agrees with Uljanin's figures of the first antennae and labrum.** C. aequoreus, Fischer, with 6-jointed first antennae, is recorded by Brady from brackish pools of salt marshes, among other places at ' Manning- tree (Suffolk).' " Manningtree itself is in Essex, but so near to Suffolk that the species mentioned is no doubt common to both counties. As to C. helleri, Brady, which that author in 1878 reported from Oulton Broad, among species with lo-jointed first antennae, in 1891 he says, ' It is perhaps more than probable that the types [now lost] represented one of the stages of development of a 1 7-jointed species, and under this impression it seems best for the present to regard the species as one of doubtful validity.' *** In the tribe Calanidea and the family Temoridae, instituted by Sars in 1 903, Eurytemora velox (Lilljeborg) is reported by Brady as occurring ' in several of the broads of Norfolk and Suffolk,' and ' in pools near the River Stour at Manningtree.' For the synonymy of this species, which involves various perplexities, the reader should consult the works of Dr. Brady and Mr. Scourfield. Both writers agree that it thrives in fresh water, and also flourishes in that which is brackish. Brady says, in brackish pools fully exposed to the rays of the sun it seems to luxuriate, often fairly swarming in such places.'^ In the tribe Arpacticidea, and the family Tachidiidae, Tachidius hrevicornis (O.F.M.) is recorded by Brady from Oulton Broad and Lake Lothing, in brackish marsh-pools." By Norman and Scott, in The Crustacea of Devon and Cornwall [iob), this species is said to be T. discipes, Giesbrecht. From the family Canthocampidae Canthocampus minutus (O.F.M.) has been taken at Lowestoft. It has been pointed out by Canon Norman that ' Jurine himself quotes Muller's Cyclops minutus as a synonym for his own Monoculus staphylinus,' so that the latter specific name must give way to its predecessor." C. palustris, Brady, was taken by that author in brackish pools by the River Stour, at Manningtree, and in Oulton Broad (Suffolk).'* The variable species Dactylopusia tisboides (Claus), referred by Sars to the family Thalestridae {Crustacea of Norway (1905), v, 125), is reported by Brady from ' brackish pools near the River Stour, at Manningtree, Suffolk.' " Lastly, concerning Platychelipus littoralis, Brady, in the family Nannopidae, at its institution in 1880, the often-quoted author remarks, ' several examples of this very distinct species were noticed in a gathering from between tide-marks at Lake Lothing, Suffolk, where the water of Oulton Broad finds its way to the sea. Though the gathering was made among the fronds of Fuci the water would no doubt be brackish.' " A hundred years ago, so far as appears, the carcinology of Suffolk was a simple blank. Its chronicles are still extremely incomplete. No mention, for instance, has been made of cirripedes, although none of our coasts are left unfrequented by species of that group. For these and an indefinite number of other crustacean families, it is assuredly not the representative creatures that are wanting, but in some cases observers, and in others the published record of observations.
