and Samotherium (the unfortunate former name will presumably, as 

 previously stated by me, supersede the latter) ; it is therefore probable 

 that its anterior and posterior limbs were of approximately the 

 same relative length as in Samotheritim Boissieri, and not giraffe-like 

 as in Camelopardalis Attica. If this suggestion proves to be correct, 

 the proper name for this intermediate-sized member of the Giraffidee 

 will be Palceotragus vetiistus (Wagn,). 



The hornless skull and the teeth described under the name of 

 Alcicephalus Neimiayri in Eodler & Weithofer's paper on the 

 Euminants of Maragha (1890) belong to Samotherium Boissieri 

 (1888) ; not so the limb-bones ascribed to A. Neumayri, which agree 

 better with the size of PalcBOtragus Rouenii. 



It is but fair to state that there are labels in the Stuttgart 

 Museum to show that the Giraffoid affinity of the two fossils in 

 question had been duly recognized.

There are two specimens of this species in the Woodwardian 

 Museum, both of which were named and labelled by Salter. The 

 smaller and more perfect one, a 987 (Fletcher Collection), is first 

 mentioned, and is stated to have come from the Lower Ludlow of 

 Dudley. The larger specimen is from the same horizon of Green 

 Quarry, Leintwardine, and shows only a portion of the upper surface. 



Diagnosis. — Shell much flattened, discoidal ; very low, short 

 spire ; whorls five or six in number, much flattened, coiled into 

 a nearly flat spiral ; outer whorl with acute margin furnished with 

 small, narrow projecting band, marked off by groove from rest of 

 whorl, and bordered by a raised thread-like line above and below 

 (shown in Leintwardine specimen). On the inner whorls this band 

 lies on the suture-line and is almost hidden. Apical surface of 

 whorls ornamented with regular, equidistant, longitudinal, revolving 

 strias, 30-40 in number. At about one-third the distance from the 

 outer margin is a raised thread-like line or keel, parallel to the 

 strifB and more conspicuous on the inner whorls. Umbilical surface 

 of shell flattened or very weakly convex, swelling slightly 

 towards the mouth (which is not preserved). This surface is 

 oi-namented with revolving striae, similar to the apical surface, 

 but there is no raised thread-like line or keel amongst them. 

 Umbilicus deep, circular, and about one-fifth the width of the base.
