lations. Dorsal and caudal dusky ; ventrdls, anal, and 

 pectorals whitish, the latter margined and deeply pointed 

 with dusk}'. Head five and a quarter. Depth four and 

 two-thirds. D. 12. A. 11. Scales 9-86-8. Length 

 about twelve inches. 



Although, in some details, it bears a close resemblance 

 to C. Co?/gs/ Miller, and in others to C. Williamsoivi 

 Girard, it is evidently a local variety of C. quadrilateralis 

 Rich., which occurs in the lakes of New Hampshire and 

 and the upper Great Lakes of Canada. Its habits are 

 about the same as those of C Idbraduricus, except that it 

 is more frequently taken in summer about the mouths 

 of inlets, while C. labrodoririis prefers the lakes proper. 



About the middle of September the Avhite-fish congre- 

 gate around the mouths of inlets, up wliich they swarm 

 to deposit their spawn. Brush and hurdle weirs are 

 built across these streams, with nai-row gates or openings 

 through which the iish pass to lincl themselves entrapped 

 in net pounds surrounding the entrances, and so cleverly 

 arranged that the imprisoned fish cannot escape. Li 

 some phices a mere pretence is made of complying with 

 some law or custom for ])roviding a tree passage, narrow 

 though it be; but in many instances this passage is so 

 narrow and shallow that a fish could not get through 

 without danger of stranding. In the face of such de- 

 tructive fishing, it is a matter of surprise that they main- 

 tain themselves in even their present diminished numbers, 

 as compared with their abundance in former years. 

 When so taken, all are gravid and on their way to the 

 spawning grounds a few miles from the lakes. Indeed, 

 it is quite evident to any one visiting the lake region of 

 the upper St. John, and at all conversant with the habits 

 of the white-fish, that there is pressing need of the en- 

 forcement of stringent regulations to preserve to the people
