from Lower Coal-measures, Lancashire. 443 



noticed in the original examples from Nova Scotia, and I referred it 

 in my description to Dr. Dawson's species Xylobius sigillarice} 



The specimen here figured (Fig. 4) from near Colne, Lancashire, 

 shows only a part of the body of a Myriopod, consisting of about 

 25 rounded segments, truncated at the larger anterior end by the loss 

 probably of the half of the nodule in which the animal is imbedded, 

 the part preserved being the posterior or caudal moiety with its 

 counterpart. Each somite or segment has a raised ring or ridge 

 passing around near the anterior border, having (so far as exposed 

 upon the matrix) a single row of upwards of 10 minute oblong 

 bead-like ornaments on it, with a plain, slightly raised moiety forming 

 the posterior articular boundary of each segment. Beyond the first 

 13 or more anterior segments, counting from the truncated end, the 

 body-rings gradually diminish in size towards the posterior extremity, 

 which is slightly curled round like the tail of the letter J. Length 

 of the entire body about 6 cm. Length of six segments 20 mm..

width of anterior segment 8 mm. Minute walking-legs, about 5 mm. 

 long, are to be seen for almost the entire length of the body , there 

 are two pairs (where preserved) to each segment. 



The interest attaching to this specimen of Xylobius consists in the 

 preservation of the extremely beautiful ornamentation on the body- 

 segments, reminding one of the jointed columns of some Silurian 

 Crinoid such as Gissocrinus or Gothocrinus. It is to be regretted 

 that the remainder of the nodule has not been preserved, as we 

 might then have been able to describe the head, and have ascertained 

 the entire length of the body. 



Locality and formation : Soapstone bed, Lower Coal-measures, 

 Colne Hill, Lancashire. In the collection of Mr. Peter Whalley. 



Amongst the nodules sent up by Mr. Whalley there is in one the 

 remains of a fish, Acanthodes Wardii ; another contains two very 

 small Gasteropods which have not been identified. 



Mr. G. C. Crick, F.G.S., has kindly examined two other nodules 

 for me, and writes as follows : —
