II. Macrurous Crustacean. Palceopemphix, gen. nov., with three 

 new species. These carapaces doubtless belong to some small 

 Macrurous Decapod, but it is not easy to recognize their ancestral 

 relationship to Pemphix of the German Muschelkalk. The rostral 

 portion of the carapace is curiously stunted (as in the Crangonidm), 

 and the antennal (antero-lateral) angles very prominent. These 

 Sicilian forms are all seen in profile, but most of the early Carboni- 

 ferous genera had the carapace flattened out, dorsally, as in the 

 Eryonidce of the Liassic and Oolitic period, and in the recent 

 Folycheles. 



III. Brachturous Crustaceans. Paraprosopon, gen. nov., with 

 one new species. This seems to belong to the genus Cyclus of 

 De Koninck, and closely resembles G. Jonesianus, H. Woodward, in 

 particular (see Geol. Mag. 1870, Vol. VII. PI. XXIII. p. 558, 

 Woodcut, Figs. 1-2). 



IV. Oonocarciniis, gen. nov., with 3 new species. This form, 

 according to the author, has its nearest ally in HemitrocJiiscus para' 

 doxus, Schauroth. It has, however, very much of the form of 

 Caryon, Barrande, and reminds one of the head in SpJicerexochus. 

 But most of all Oonocarcinus resembles the coalesced segments of the 

 buckler-like abdomen of the female in the Leucosiadce (cf. Bell, Mon. 

 Leiicosiadce, Trans. Linn. Soc. 1855, vol. xxi. p. 277, pis. xxx.-xxxii.). 



Perhaps it may represent a part of an early Brachyurous Decapod; 

 if so, it has an additional interest for us. 



V. Ostracoda. Cypridinella, Jones & Kirkby, 2 new species ; 

 Cypridellina, J. & K., one new species ; Cypridella, De Koninck, 2 new 

 species; Cypridina, Milne Edwards, 2 new species; PMlomedes, 

 Lilljeborg, 1 new species ; Entomoconchus, M'Coy, 1 new species ; 

 Entomis, Jones, 2 new species ; Beyrichia, M'Coy, 1 new species. 

 These have an exceedinglj' close resemblance to the true Carbon- 

 iferous species of Britain and Belgium, and at first sight might in 

 most instances be taken for them. The figured " Beyrichia," how- 

 ever, is a very doubtful specimen. 



In bringing together the members of this most interesting local 

 fauna, and illustrating it in so clear and admirable a manner, the 

 author has done good service to Palasontology, and deserves our best 

 thanks. H. W. & T. E. J. 



II. — British Pliocene Vertbbrata. 



" The Vertebrata of the Pliocene Deposits op Britain." By 

 E. T. Newton, F.G.S., F.Z.S. Mem. Geol. Surv. United 

 Kingdom, 1891, pp. i-xii, 1-137, PI. I.-X. 



THROUGH the generosity of the author we have been favoured 

 with a copy of this valuable Memoir, which forms a companion 

 volume to Mr. Newton's well-known work on " The Vertebrata of 

 the Forest Bed Series of Norfolk and Suffolk," published by the 

 Geological Survey in 1882. The Memoir also seems to have been 

 prepared in connexion with another Survey publication by Mr. 

 Clement Eeid, " The Pliocene Deposits of Britain," said to have
