Eitter-Zahony gives the upper limit of S. elegans as 30mm. and of 8. elegans 

 arctica as 44mm. Our measurements would indicate that 8. elegans reaches a length 

 of 36mm. (an individual from the Bay of Fundy, (which is almost in the region from 

 which the species was first described, measured 35mm.), and 8. elegans arctica a length 

 of 52mm. 



The majority of the larger specimens are sexually mature, but even some of the 

 largest are immature. The size at which maturity is attained apparently varies with 

 the region. JSTo measurements of the sexual organs were made, but on examining 

 material from a number of points and observing the state of the ovaries and seminal

vesicles it was seen that in the Bay of Islands No. S3 station 57), the sexual organs 

 were maturing only when a length of 30mm. was reached (but even as low as 22mm. in 

 a catch by the young fish trawl); northern part of gulf {Princess station 16), 23mm.; 

 middle part of gulf (Princess station 33), 23mm.; southern part of gulf (Princess 

 station 25). 20 mm.; southern coast of Newfoundland (Acadia stations 20, 35, 83), 

 24mm.; off northern end of Nova Scotia (Acadia stations 67 and 90), 25 mm.; off 

 southern part of Nova Scotia (Acadia station 38), 24mm.; in the Bay of| Fundy, 

 (Prince station 1), 22mm. At Prince station 3 at the mouth of the Bay of Fundy, the 

 specimens even as large as 35mm. had immature ovaries. Other factors are doubtless 

 involved.
