On some Fossil Myriapods from Forfarshire. 179 



Powrie's and the Survey specimens bear testimony to the 

 correctness of my surmise. 



After a long and careful study of all the specimens obtain- 

 able, I find that there are two distinct forms which have 

 both probably been included in the genus Kampecaris. Tlie 

 characters of these are such as to warrant their being looked 

 upon as belonging to two distinct genera of Chilognathous 

 Myriapods, which differ from all recent and all hitherto- 

 described palaeozoic genera in having each body ring single, 

 and each bearing only one pair of legs. 



Genus Kampecaris (Page). 



Body long and cylindrical, with scarcely any taper to- 

 wards its anterior extremity ; almost circular or slightly de- 

 pressed in cross section, and composed of numerous alternately 

 larger and smaller somites, each bearing only one pair of limbs. 

 Test granulated and supplied on dorsal scutes with occasional 

 papillae supporting spine-like hairs ; lateral lamellae small. 



The retention of Dr Page's name for this form is proposed, 

 as it is evident that it is the one that has been fioured. 



Kampecaris Forfarensis (Page). — PL II., figs. 1-19. 



Body long and cylindrical, with little or no taper an- 

 teriorly, composed of several free segments which are larger 

 and smaller alternately. Sixteen of these in one specimen 

 measure on an average 20 mm., the average breadth being 

 4*5 mm. for the larger and 3-5 mm. for the smaller somites. 

 The latter are a little less than half the length of the former. 

 The dorsal scutes occupy about two-thirds of each somite, 

 those of the larger ones being puffed out and bearing on their 

 sides slight protuberances or lateral lamella, which are not 

 found on the smaller. The sternal plates occupy the other 

 third of the rings, and are pierced near their external margins 

 by the holes for the insertion of the coxae of the limbs which 

 are oval or reniform, and placed with their long axes obliquely 

 to the length of the body, and with their anterior ends look- 

 ing inwards, so that the coxae of the succeeding somites
