some of the specimens of that genus from 
Scaumenac Bay threw quite a new light on 
the structure of its mouth organs and of 
the so-called ‘lid’ with its pineal element. 
And, similarly, a portion of one side of the 
head of a specimen of Eusthenopteron from 
the same locality, which by an oversight 
was referred to Phaneropleuron, has almost 
all the sclerotic plates of the eye preserved. 
From the collections made near Camp- 
bellton in 1881 and 1882 four species of fos- 
sil fishes were described, viz.: Cephalaspis 
Campbelltonensis ; a supposed Coccosteus (C. _ 
Acadicus), the type of Traquair’s subse- 
quently characterized genus Phlyctenaspis,* 
and two kinds of fin spines. 
Numerous fossil fishes from both of these 
localities have since been collected by Mr. 
Jex for Mr. R, F. Damon, of Weymouth, 
England, and these have been acquired by 
the Edinburgh and British Museums. These 
later collections have yielded some addi- 
tional species, one from Scaumenac Bay, 
which was described by Dr. Traquair in 
1890, and six from Campbellton, three of 
which were described by Dr. Traquair, one 
in 1890 and two in 1893, and three by Mr. 
A. Smith Woodward in 1892. The latest 
novelty from Scaumenac Bay is a new 
Cephalaspis (C. laticeps, Traquair), of which 
it is said that ‘‘ this is the first occurrence 
of a cephalaspid in rocks of later age than 
the Lower Devonian.’’+ The three addi- 
tional species from Campbellton that Dr. 
Traquair has described are two ichthyo- 
dorulites ( Gyracanthus incurvust and Cheira- 
canthus costellatus)§ and another Cephalaspis 
(C. Jexi).|| The three from the same lo- 
cality described by Mr. A. Smith Wood- 
ward, in the eighth volume of the Third 
Decade of the Geological Magazine, are all

elasmobranchs, viz., Acanthodes semistriatus, 
Protodus Jexi and Diplodus problematicus, 
the latter being the type of Traquair’s genus 
Doliodus,* published in 1893. 
In 1882 Sir William Dawson determined 
or described the fossil plants from Scaume- 
nac Bay, four specifically and four only 
generically, and identified six species of 
fossil plants from near Campbellton with 
the Psilophyton prineeps, P. robustius, Arthros- 
tigma gracile, Leptophleum rhombicum, Cor- 
daites angustifolia and Prototaxites Logani of 
the Gaspé sandstones. He asserts that the 
plant and fish-bearing beds at Scaumenac 
Bay are ‘‘no doubt the equivalents and 
continuation of the upper part of the Gaspé 
sandstones,’’ and that the fossil plants from 
near Campbelltown are ‘‘ perfectly identical 
with the lower part,’’ of these sandstones. }

THE FAMILY NAME OF THE DORMICE. 
In a paper ‘On the Genera of Rodents,’ 
published in 1896,{ Mr. Oldfield Thomas 
‘very properly rejected the family name 
Myoxidze commonly applied to the Old 
World dormice, for the reason that Myoxus, 
on which it was based, is a synonym of the 
earlier generic name Glis. In adopting 
the name Gliride he divided the family 
into two subfamilies, Glirine and Plata- 
canthomyine ; the former including four 
genera: Gilis Brisson, 1762; Muscardinus 
Kaup, 1829; Eliomys Wagner, 1843, and 
Graphiurus Cuvier, 1838; the latter Plata- 
canthomys Blyth, 1859, and Typhlomys Milne- 
Edwards, 1877. It now appears that 
Gliride is untenable for this family because 
of previous application to other groups ; in
