H. Woodivard — Neio Pkyllopodous Crustaceans. 105 



directed by Mr. Lightbody to a truly remarkable fossil from the 

 collection of Mr. Henry Pardee, and obtained by him from the 

 Lower Ludlow, Church Hill, Leintwardine. It consists of seven 

 body-segments and three caudal spines, of the largest example of 

 Ceratiocaris I have ever seen ; exceeding in size the C Bohemicus of 

 Barrande, or C. MurcMsoni from the Upper Ludlow Eock, Ludlow 

 and Wenlock Shale, Dudley, figured and described by me in the 

 Geological Magazine, 1866, Vol. III., PL X., Fig. 8, pp. 203-205. 

 The figure (taken from a sketch made at the time) given on Plate III., 

 Fig. 3, being only one-third the size of the fossil, conveys but a very 

 inadequate idea of this interesting Crustacean remain. The seven 

 body segments together measure eight and a half inches in length, 

 and nearly two inches in breadth ; they are nearly quadrangular, 

 and are covered with fine and delicate parallel slightly waved strise. 

 The first segment is three-quarters of an inch long ; the second, half 

 an inch ; the third, three-quarters of an inch ; the fourth, fifth, and 

 sixth, one inch each in length; and the seventh, two and three- 

 quarter inches long. Their articular faces do not overlap, and are 

 nearly straight, save the sixth, which has a small rounded articular 

 process fitting into a corresponding depression in the seventh seg- 

 ment, which at its distal extremity is also furnished with an articular 

 process, to which the tail-spines are united. The tail-spines are not 

 pitted, but are very robust, and are six and a half to seven inches in 

 length, and nearly half an inch broad at their proximal end. Unfor- 

 tunately, the carapace of this giant Phyllopod is wanting ; but taking 

 the comparative proportions of C. papilio from Lesmahagow as our 

 guide, it could not have measured less than eight inches in length, 

 by four and a half inches in breadth. 



I propose to name this new species Ceratiocaris Ludensis. 



2. Ceratiocaris Oretonensis, H. Woodw., Plate III. Fig. l(nat. size). 



Among the large series of fossils acquired by the British Museum 

 from the collection of the late Mr. Edward Baugh, of Bewdley, are 

 two new forms of Ceratiocaris, which were obtained from the 

 Yellow Carboniferous Limestone of Oreton and Farlow, Worcester- 

 shire. (See Plate III., Figs. 1 and 2, figured of the natural size). 



They agree closely in form with certain Upper Silurian species 

 found at Benson's Knot, Westmoreland ; but are destitute of the 

 beautiful and delicate striated ornamentation observable upon the 

 carapaces of those species. 



The larger form (Plate III., Fig. 1) measures two inches in length 

 by seven-eighths of an inch in depth ; the dorsal line is nearly 

 straight, the anterior end is rounded, the posterior slightly produced 

 and truncated ; the ventral margin is rounded, and has a slightly 

 raised border for about three-fourths of its length ; the valves of the 

 carapace are tumid, and when perfect appear to have been smooth 

 and free from ornamentation, like the valves of Leperditia : the eye- 

 spot is not very distinct, but forms a slightly raised prominence near 

 the anterior end of the carapace. I propose to name this new and 

 large Carboniferous species Ceratiocaris Oretonensis.
