8 DEPARTMEl\'r OF THE NAVAL SERVICE 



As will be seen from the chart, ova and young were only found at the stations 

 nearest the coast, especially in the gulf of St. Lawrence along Prince Edward Island 

 and Cape Breton. 



The material of this species from the Acadia amounts to some few eggs and young 

 taken at Sable island and farther in near the Gut of Canso. 



The size of the young varied between 3 and 9 mm.; (see also tables), 



2. FAN. CARANGIDJE. 



Capros aper (Lacepede). 



,0f this species, only one specimen (total length 6 mm.) was taken, this being 

 from the Acadia, Station 44, where it was brought up in a vertical haul from 150-0 

 m. ' Although Jordan and Evermann do not mention this species as occurring in 

 American waters, I have been obliged to ascribe this specimen to the si)ecies in 

 question. C. aper is also found, by the way, in the eastern Atlantic right up to the 

 coasts of England, and it also penetrates into the Mediterranean. 



3. FAM. SC0MBRID2E. 



Scomber scornbrus (Linnaeus). 



(Plate I, Fig. 3: Table lib.) 



Of this species, quite a considerable quantity both of ova and young were 

 collected, especially by No. S3, and on the second cruise of the Princess. 



Jordan and Evermann give the distribution of the mackerel along the American 

 coast as from Labrador to cape Hatteras, and it is therefore remarkable that its ova 

 and young should here have been found almost exclusively in the southern portion of 

 the gulf of St. Lawrence. The cruises of the Acadia furnished but three eggs from 

 stations outside Nova Scotia, and neither the Princess nor No. 33 found ova or young 

 of mackerel in the northern part of the gulf.
