Raia erinacea, Mitchill. 
Very abundant in the Bay of Fundy and Passamaquoddy bay, occurring 
in the latter from May to December or even January, and in the Bay of Fundy 
somewhat longer. Young skates have never been found in Passamaquoddy 
bay, but what appear to be the young of this species have been taken just out- 
side Passamaquoddy bay off Campobello island in 50 fathoms, although only 
during February and March. Similar young skates were taken in Minas chan- 
nel in September, 1920. Doubtless the head of the Bay of Fundy is a breeding 
ground from which the young descend toward the mouth of the bay during 
winter. Taken in seines, weirs, shrimp and beam trawls and on long lines. 
Also observed in Minas channel and basin, at Harbourville, Kings County, and 
in Annapolis basin and St. Mary bay. Perley (1852, p. 225) reported it from 
Grand Manan. 
Raia diaphanes Mitchill. 
syn. R. ocellata. 
Abundant both in the Bay of Fundy and Passamaquoddy bay, occurring 
in the latter from May until November. No young are seen, but the half 
grown are difficult to separate from R. erinacea. Taken in weirs and shrimp 
trawl, and on long lines. Also in Minas channel and St. Mary bay. 
Raia radiata, Donovan. 
Frequently taken with the other skates in Passamaquoddy bay from May 
to November, but never in shallow water, always in depths of 10 fathoms or 
more. It seems to remain in the Bay of Fundy throughout the winter, as we 
obtained it off Campobello island in February and March of 1919, the only 
adult skates which we secured at that time of the year. Captured in the shrimp 
trawl and on long lines. We have also taken it in St. Mary bay, but only in 
the deeper water (20 to 30 fathoms). No young, identified as this species, 
have been taken. Cox (1896 a, p. 75) reports having obtained it off St. Martins 
in St. John county, near the head of the Bay of Fundy. 
Raia stabuliforis, Garman 
syn. R. laevis Mitchill. 
Adults of this species are never abundant, but are found very generally 
in Passamaquoddy bay and the Bay of Fundy. In the former they are to be 
found from May until November, and somewhat longer in the latter. No young 
have been found. Taken in weirs and shrimp trawl, and on long lines, or 
captured almost stranded by the ebbing tide in shallow water. Also taken in 
Minas basin and channel, at Morden, Kings county, and in St. Mary bay. 
Jones (1879, p.97) with Gilpin as authority, reported it from the Nova Scotian 
coast in the Bay of Fundy, and Perley (1852, p. 224) gave near the eastern end 
of Campobello island and the Annapolis basin as localities for its occurrence.
