of the joints of the left antenna are left, though these are 

 still attached to the head. 



Body. — The body is elongated and fusiform, though the 

 segments are somewhat flattened, and produced into distinct 

 lateral lamellae, while the dorsal portion of each segment is 

 ornamented with an embossed sculpturing, like that seen upon 

 corresponding structures of species of the recent Polydesmiis 

 (Fig. 3'^). The first segment, counting from the head back- 

 wards, is a little narrower than the back of the head, 

 while this and the following two appear to be single, the 

 third from the head being the deepest. All the rest of the 

 segments are double. The body appears to attain its 

 greatest breadth of 3 mm. about the seventh segment, and 

 from thence it carries this breadth to within a short distance 

 of its extremity, where it tapers somewhat suddenly towards 

 its terminal joint, which is almost half-moon shaped, with a 

 breadth of about 1 '5 mm. at its articular base. None of the 

 sternal arrangements are observable. 



Limbs. — Most of the legs have been removed prior to 

 fossilization, but from the few fragments left, they appear 

 to have been constructed much after the manner of those of 

 the recent Polydesmidse. 



Locality. — Lennel Braes, Coldstream, Berwickshire. 



Formation. — Calciferous Sandstones, Lower Carboniferous. 



Collector. — A. Macconochie. 



Genus Kampecaris (Page). 



Kampecaris Obanensis. 



[Plate IV. Fig. 2.] 



This specific name is proposed for a small form of 

 Kampecaris, from the Lower Old Eed Sandstone rocks of 

 the island of Kerrera, near Oban. The specimen, preserved 

 in dark flagstone, is doubled together and flattened by 

 pressure, so as to expose only the dorsal aspect of part of 

 the back and the right side. It is slightly curved, and 

 measures about 20 mm. in length. 



Head. — The head, as viewed, is subquadrate in shape.
