(PLATE IX.) 



A CAREFUL examination of four fossil millipedes from the 

 Middle Coal-measures of Sparth Bottoms, Rochdale, three 

 preserved in the Manchester Museum and one in Mr. H. Howard's 

 private collection, has revealed some striking features which seem to 

 justify a re-description of the whole material. 



These four specimens were originally described by "W. Baldwin in 

 Geol. Mag., 1911, pp. 74-80, Pis. III-V. 



The first example to be dealt with is that described as 

 Acantherpestes giganteus. (Text-fig. 1, 2; PI. IX, Fig. 1.) 

 [Nos. L 9941 and L 9942, Man. Mus.] 



This specimen was obtained by Baldwin in June, 1910, and is 

 the type of his species. The dimensions are those given in the 

 original description. 2 The animal was preserved in a large nodule 

 w T hich, on being split, exhibited both an impression of the dorsal 

 surface and a cast showing the structure of the dorsal plates as well 

 as some of the more ventral features of the animal's body displaced 

 somewhat to the left. A glance at the impression, which exhibits 

 some nineteen body segments, is sufficient to show that we are 



The earlier papers in this series have appeared in various scientific 

 publications.
