nised. In the first edition of his "Advanced Text-Book," 

 the late David Page affixed the name of Kampecaris For- 

 farensis,* or the Forfarshire grub-shrimp, to one species, under 

 the impression that it was an anomalous larval form of Isopod 

 crustacean, and subsequent writers seem to have acquiesced in 

 his dictum. Salter and Woodward, in their " Chart of Fossil 

 Crustacea,"-f* give a figure of the Kampecaris Forfarensis, which 

 is evidently taken from a specimen presented by the late Sir 

 Philip Egerton to the Geological Survey, and now in their 

 collection in Jermyn Street, London. 



In the year 1873 C. W. Peach, while arranging the geo- 

 logical collection belonging to the Watt Institute, Dundee, 

 saw that one of the specimens from the Lower Old Eed 

 sandstone of Forfarshire, now about to be described, was a 

 portion of a myriapod. About the same time, Walter 

 MacNicol of Tealing, near Dundee, an enthusiastic local 

 geologist, presented him with two other specimens from 

 the same county. All these Mr Peach showed to Henry 

 Woodward, the great authority on fossil Arthropods, who 

 corroborated his opinion, comparing them at the same time 

 with the carboniferous Euphoberia of Messrs Meek and 

 Worthen, from which genus, however, they differ in some 

 very essential points. Last year C. W. Peach drew my 

 attention to these fossils, and I saw that one of these 

 myriapods was the Kampecaris of Page. To make certain 

 of the matter, I endeavoured to obtain some of Dr Page's 

 specimens, and I applied to James Powrie, Esq. of Eeswallie, 

 F.G.S., whose collection of Forfarshire fossils is well known 

 to be the best extant. Mr Powrie generously put his speci- 

 mens at my disposal, and one of these, a slab with the remains 

 of several different individuals of Kampecaris, had been pre- 

 sented to him by Dr Page himself Professor Archibald 

 Geikie, LL.D., F.E.S., Director-General of the Geological 

 Survey of Great Britain and Ireland, has kindly brought 

 down to Edinburgh the specimen figured by Salter from the 

 Jermyn Street collection for my inspection. Both Mr
