and stands farther back than the corresponding spine of L. Americana. The 

 second dorsal resembles the anterior one in its first ray, which is spinous, being the 

 highest, the succeeding articulated ones gradually diminishing in altitude. The 

 two fins are equal in height, while in L. Americana the posterior one is lowest. 

 In profile, the resemblance of the Green pickering to the Sandres is pretty close, 

 but it presents a very dissimilar section of the body. Lieutenant-Colonel Smith 

 remarks, that it has a strong similarity in form to the Aspro vulgaris, though it 

 cannot rank in the same genus, as its dentition is totally different, nor does its 

 likeness to that fish extend to the form of its jaws and caudal. We have been 

 favoured with the following extract from Lieutenant-Colonel Smith's original 

 notes respecting this interesting species. 



" The specimen was caught at Quebec in the month of October, and measured about four- 

 teen inches in length. The hack was broad and flattish, its breadth nearly equalling the 

 depth of the body. The gape large, extending to the eyes ; the teeth strong, obtuse and 

 standing singly. Nostrils double. Edge of the gill-plate armed with a row of five spines, 

 which do not extend beyond the bordering membrane. Head scaly and the body rough, and 

 stiff with very small scales. The two dorsals have an interval between them, and the first is 

 marked with three rows of large, round, black spots ; the second with four streaks of the same 

 colour : the tail is lunate, with a half-black bar on the upper and lower rays : — these three 

 fins, together with the pectorals, having a yellow ground colour. The anal, commencing 

 under the seventh ray of the second dorsal, is ochre-yellow : the ventrals are rounded and 

 have a bright orange tint. The irides are black with a golden ring. The upper part of the 

 body is dark olive-green, the lower whitish, joining the black by a waving line : there are 

 a few pale yellow spots below the lateral line which curves downwards.

This fish inhabits Lakes Huron, Ontario, and Erie, frequenting, during the 

 summer months, shady places, under high banks or shelving rocks. It preys upon 

 cray-fish, worms, and the larvae of coleoptera, and is very voracious, not sparing 

 the young even of its own species. Our specimen, which was procured at Pene- 

 tanguishene, was submitted to the inspection of Baron Cuvier, who made the fol-
