Type. Pish wanting head and anterior half of abdominal region ; 
collection of James Powrie, Esq., Reswallie. 
A species about 0’2 in length. Body much elongated : spines 
comparatively straight. Eour or five pairs of intermediate ventral 
spines, separated by a distinct interval from the pelvic fin-spines ; 
the latter more than half as long as the anal spine. Eirst dorsal 
spine shorter than the second, about midway between the pectoral 
and pelvic pairs; second dorsal spine much larger than the anal, 
well in advance of the latter, almost opposed to the pelvic spines. ’ 
Lateral line with double series of enlarged scales. ( Powrie .) 
Form. <Sf Log. Lower Old Red Sandstone: Farnell, Forfarshire. 
Hot represented in the Collection. 
The so-called Euthacanthus eleyans, Powrie (tom. cit. 1870, p. 292, 
pi. xii. fig. 5), is founded upon an imperfect impression of a fish from 
Farnell, only differing from Climatius gracilis in the proportions of 
some of the spines, which may be imperfectly shown. Another 
species, Euthacanthus curtus, Powrie (ibid. p. 293, pi. xii. fig. 7), 
from Turin Hill and Farnell, does not appear to belong to this 
genus, and is doubtfully referred to Diplacanthus by Woodward and 
Sherborn, Cat. Brit. Foss, \ertebrata (1890), p. 65. The type speci¬ 
mens are in the collection of James Powrie, Esq.
