in 1880,* T88it and 1883,$ and described and illustrated in 
i887§ and 1889.H Many of these specimens were exhibited and 
described at the meeting of this association at Montreal in 
1882. 
In the collections from Scaumenac bay made up to 1882 
and described by the writer, the Elasmobranchii are repre- 
sented by two species of Acanthodes (A. concinnus and A. af- 
fmis) ; the Ostracodermi by numerous, remarkably well pre- 
served and nearly perfect specimens of a Bothriolepis (B. can- 
adensis) which Gesner seems to have thought was a small 
tortoise ; the Dipnoi by a supposed Phaneropleuron (P. cur- 
tum), the type of Traquair's subsequently described" genus 
Scaumenacia;^and the Teleostomi by a Glyptolepis (G. que- 
becensis), a Cheirolepis and a new genus (Eusthenopteron) 
closely allied to Tristichopterus. A few of the superficial and 
presumably sensory grooves on the cranial shield of the Canad- 
ian Bothriolepis were mistaken for sutures, as the similar ones 
of the European species had been by Lahusen, but 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 Campbellton in 1881 and 
1882, four species of fossil fishes were described, viz., Ceplia- 
laspis campbelltonensis ; a supposed Coccosteus (C. acadicus) 
the type of Traquair's subsequently characterized genus 
Phlyctoenaspis,** and two kinds of fin spines. 
Numerous fossil fishes from both of these localities have
