Pomolobus aestivalis (Mitchill). 
Seemingly restricted to the larger rivers. Cox has found it in the St. John 
river, and we have had specimens from St. John harbour and the Shubenacadie 
river. However, Bensley (1901, p. 61) has reported it doubtfully from Passa- 
maquoddy bay, and Kendall (1908, p. 39) has recorded it from Eastport in 
two collections. 
Alosa sapidissima (Wilson) 
Spawning in the large accessible rivers, as the St. John, Petitcodiac, Shu- 
benacadie and Annapolis, its distribution in salt water being restricted largely 
to the regions near the mouths of these rivers. Rarely taken in Passamaquoddy 
bay, where it must be considered as a stray from the St. John, whose fishery 
does not extend beyond the border of the county at Lepreau. The shad from 
the Shubenacadie and neighbouring rivers go to sea for a greater distance, 
probably owing to the peculiar hydrographic conditions at the head of the bay. 
The fishery extends through Minas basin and channel to the Annapolis county 
line or farther. Taken in gill nets and weirs. Formerly in the St. Croix river 
(Atkins, 1887, p. 700). : 
Brevoortia tyrrannus (Latrobe). 
Perley (1852, p. 208) referred to this species being sometimes taken in the 
weirs in St. John harbour, and in 1919 we received from Overseer Brittain a 
specimen of this species taken in that harbour on August 12th. We have never 
seen it in the Western Archipelago. Kendall (1908, p. 40) gives Goode, 1877, 
as authority for its occurrence in Passamaquoddy bay, which seems at variance 
with Goode’s account of the species in 1884. An immigrant from the south. 
Coregonus quadrilateralis, Richardson. 
Two specimens of a Coregonus doubtfully identified as this species by Dr. 
Cox, were seined in mid-channel at the mouth of the Sissibou river, St. Mary 
bay, on September 8, 1919. In James and Husdon bays it is customary to find 
whitefish and ciscos in brackish or salt water, but this appears to be the first 
recorded instance of this kind for our Atlantic coast. 
Oncorhyncus gorbuscha (Walbaum). 
This Pacific species has been introduced by the United States Bureau of 
Fisheries into the waters of northern New England. The fish have been ob- 
served at Lubec and in Cobscook bay (Fisheries Service Bulletin, No. 67, 1920). 
Humpback salmon were reported to have been taken in weirs in Passamaquoddy 
bay, both in 1919 and in 1920, but we were unable to secure any specimens for 
examination. 
Salmo salar L. 
Its abundance in the salt water is determined by the proximity of a river 
system suitable for spawning. Now rare in the Western Archipelago since- 
the damming of the St. Croix river, the few that are taken being doubtless
