FISH, EEPTILES, AND INSECTS OF LAPLAND. 163 



Lloyd mentions killing in one day, 50 brace of 

 grayling in a tributary of the Kemi river, 69 north 

 lat., weighing upwards of 100 Ib. 



The burbot were neither large nor numerous, 

 andthe season for them closed just after we cameup. 



The perch were remarkably fine and large in 

 these waters. We often took 60 Ib. or 70 Ib. in 

 one large bow-net in a night. I observed that we 

 seldom saw one under | Ib., and 3 Ib. was not an 

 uncommon size. Some years since a kind of 

 epidemic raged among the perch here, and nearly 

 all were swept off, but they are now recovering 

 their numbers again. 



We had certainly two species of gwynniad here. 

 The Coregonus oryrliinrhus, Nilss. (Nabb-sik, 

 Swed.), and the Coregonus Lavaretus (or Lof-sik, 

 Swed.). We used to take both in the same haul 

 of the net, but the C. Lavaretus was by far the 

 rarest. It is said they are often taken up to 8 Ib. 

 I never, however, saw one above 5 Ib. There is 

 a smaller species here, at least they used to con- 

 sider it a distinct species, which they called the 

 " asp," a name, however, which we use in the 

 middle of Sweden for a very different fish, the 

 Cyprinus Aspius, Lin. They always ran small, 

 and I never saw a specimen over 8 inches ; but 

 they were always full of roe or milt, in June and 

 July, whereas I never then saw any roe or milt in
