5 to 5 "5 inches lon£^, by 4"8 broad. Successive prints 

 separated by about 16 inches. No indication of the 

 digits. Track comparatively narrow. (Jard., '53, plate /.). 



ChelicJmtis plagiostopus, Jard. A track of very closely 

 set impressions. Each impression probably consisted of 

 an obliquely set line of digits only. They are all covered 

 with matrix. Track wide compared with the short stride. 

 (Jard., '53, plate X). 



Harkness described and named a number of impres- 

 sions, but did not figure them. (Hark., '51). 



ChelicJinus planciis. Hark., is a little chelichnoid print, 

 only f inch across the pes, with a tiny manus \ inch broad 

 nearly covered by the pes, from Locherbriggs, Craigs, 

 and Green Mill quarries. It would seem to fall near CI. 3. 

 {Plate III., Fig. 22). 



Batrichnus Stricklandi, Hark., differs from CI. 3 chiefly 

 in size, the pes being usually under i inch in length. 

 Green Mill Quarry. 



Sanrichnus acutiis. Hark., appears to be almost exactly 

 like a small x\ {Plate III., Fig. 16), with the "sole" fairly 

 well impressed in some cases, but usually slight. Entire 

 print slightly under i inch long. It cannot be far from 

 A'3 {Plate /., Fig. 3). Green Mill quarry. 



ChelicJnms obliquus, Hark., appears to be a small 

 chelichnoid form, with prints about i inch broad, inclined 

 slightly outwards on the track, and with a stride of about 

 8 inches. Green Mill quarry. 



Chelaspodus Jardini, Harkness, appears to agree in 

 some respects with Actibates, but is slightly smaller, with 

 the prints still more closely set in the track. It usually 

 shows four marks in each print.
