64 EEPORT — 1889. 



carapace-valve is rounder. This unique specimen belongs to the Wood- 

 wardian Museum, Cambridge. 



V. Nothozoe. — If NotJiozoe, Barrande, be reckoned among the Phyllo- 

 poda ^ R. P. Whitfield's Nothozoe? Verinontana should be noticed. It is 

 nearly ovate in shape, |x| inch in dimensions. From the Potsdam 

 sandstone of Vermont, U.S. ' See ' Bullet. Amer. Mus. Nat. Hist.' vol i., 

 No. 5, p. 144, figs. 14 and 15 (1883 ?). 



VI Protocaris. — Protocaris Marslii, "Walcott, ' Bullet. U.S. Geol. 

 Survey,' No. 10 (1884-5), p. 50, pi. 10 ; No. 30 (1886), pp. 147, 148, 

 pi. 15, fig. 1, appears as a compressed Apudiform organism, with a 

 flattened, subquadrate, obscure cephalothorax, and a tapering body or 

 abdomen of ' 30 narrow segments, a large terminal segment or telson, 

 with two rather strong caudal or terminal spines.' ' Total length, 42 mm. ; 

 length of carapace, 21 mm. ; width, 26 mm. ; length of body, 15 mm., 

 exclusive of caudal spines ; width of body where it passes beneath the 

 carapace, 10 ram. ; at telson, 4 mm.' From the ' Middle Cambrian, 

 Georgia Formation ; Parker's farm, town of Georgia, Vermont.' 



VII. Gerattocaris. — 1. In the ' British Association Report for 1855 ' 

 (1856),' Trans. Sections, (Part II.), pp._ 98, 99, the late Rev. W. S. 

 Symonds recorded the discovery by Mr. Lightbody in the Upper-Ludlow 

 Shales on the banks of the Teme, near Ludlow, of a fine specimen of the 

 caudal trifid appendage of a Phyllopodal Crustacean, and in the ' Edinb. 

 New Philos. Journ.,' new series, vol. ii. (1855), p. 404, pi. 8, he gave a 

 descriptive note, together with a careful drawing made by Mrs. Humphrey 

 Salwey. We have not been able to trace the ultimate disposition of this 

 interesting fossil. If the drawing gives the natural size, the specimen 

 might be said to be a gigantic form of Ceratiocaris patula, T. R. J. and 

 H. W., ' Monogr. Brit. Pal. Phylloc' 1888, p. 46, pi. 11, fig. 11. 



2. The British Museum (Natural History) has obtained the trifid 

 caudal appendage of a small Ceratiocaris (I 1007) from the Wenlock 

 Limestone of Dudley, which also resembles G. patula. 



3. A new species of Ceratiocaris has been published in the ' Trans. 

 Royal Society of Canada,' Section IV., 1888. In his memoir ' On some 

 remarkable Organisms of the Silurian and Devonian Rocks in Southern 

 New Brunswick,' p. 56, pi. 4, fig. 9, Mr. G. F. Matthew gives the 

 following : — 



Ceratiocaris pusilla, n. sp. — A small, elongate, and delicately shaped 

 Ceratiocaris, carapace 15 mm., and altogether about 30 mm. long, 5 mm. 

 wide. ' This little species occurs in myriads in the black fissile shales of 

 Division 2 of the Silurian succession at Cunningham Brook, Westfield 

 Station, N.B.' These strata are regarded as being of the age of the 

 Mayhill Sandstone. In the same black shale Mr. Matthew has found the 

 fossil fish Biplaspis, n. gen., op. cit., pp. 49-55. 



4. A Lower- Silurian (Ordovician) species of Ceratiocaris (C Geno- 

 manensis, Tromelin) is referred to in the Report of the ' Assoc. Pran9aise 

 pour I'Avancement des Sciences ; Compte rendu de la 4™^ Session, 

 Nantes, 1875 ' (8vo. Paris, 1876), p. 623, as occurring in the ' Calcaires 

 ampeliteus ' of Lusanger, and in the ' Bullet. Soc. Geol. France,' ser. 3, 

 vol. iv. 1876, in Table B, as in the same limestone at Chamire-en-Charnie, 

 Dep. Sarthe. M. Paul Lebesconte, of Rennes, has obligingly given us 

 the opportunity of examining a large series of the palaeozoic fossils from 



' Third Keport (for 1885), pp. 358, 359.
