New Myriapods from the Palceozoic Rocks of Scotland. 115 



to Sc udder's family of the Euphoberidae, Myriapods with 

 their body-rings produced into spines, and having a peculiar 

 arrangement of their ventral plates. On the death of Mr 

 Coutts, the specimen was acquired by the Museum of 

 Science and Art, Edinburgh, and, by the kind permission 

 of Dr E. H. Traquair, I now propose to lay the description 

 of it before you, and to associate it with the names of Messrs 

 Patton and Coutts, in grateful recollection of their services 

 to science. 



Genus Pattonia, nov. gen. 

 Body fusiform ; segments almost circular in cross section, 

 a little more than three times broader than deep, and set 

 with spines round their posterior dorso-lateral margins. 



Pattonia Couttsi, spec. nov. 

 [Plate IV. Figs. 1-1«.] 



The only specimen from which the present species is 

 described consists of the head and nine of the succeedino- 

 segments of a large and handsome Myriapod, which must 

 have been fusiform, and nearly circular in cross section. 

 The fragment preserved measures 40 mm. from the front of 

 the head to the posterior end of the seventh segment. The 

 matrix in which the remains are embedded consists of a finely- 

 levigated dark calcareous shale, while the head and seven 

 segQ^ents are filled in with clay ironstone, in such a manner 

 that they retain much of their natural vaulting. Only the 

 dorsal and dorso-lateral view of the segments is shown. 



The head is 9 mm. long by 8 mm. broad at its broadest 

 point. It is followed by a segment which is only 6 mm. 

 broad. From this segment backwards, each succeeding one 

 increases in breadth, till at the sixth the body has attained 

 its maximum breadth of 15 mm. The seventh segment, the 

 hindmost one, preserved in a state fit for study, is of almost 

 exactly the same proportions as the sixth. From these data, 

 it is rational to infer that only the anterior portion of a 

 much elongated animal is preserved to us, and that the 

 portion of its body which is not preserved tapered back- 

 wards. The head-mask, which is a little longer than broad, 

 is pyriform, with its narrower end in front, and broadest at
