hawk, p. 460 Couch on the characteristics of a kind of Trigla hitherto 



confounded with the T. Blochii, p. 463. The fish here described agrees in all 

 its essential characters with the Trigla noticed by Cuvier ( Poissons, Vol. iv. p. 

 67,) under the name of T. Cuculus, Bl. ; from whose description it differs only 

 in the absence of a dark spot on the first dorsal ; a circumstance which, it is 

 remarked by that author, is liable to variation. But it is distinguished from 

 Bloch's gurnard of Mr Yarrell {Br. F. p. 50,) in a variety of particulars, of 

 which the chief are, the very great difference of size, the latter " rarely exceed- 

 ing 1 foot in length, and seldom above 9 or 10 inches ;" * — " the whole body 

 rough," whereas this fish is not rougher over the body than the tub-fish is, 

 " the lateral line more strongly serrated than in the grey gurnard," whilst in the 

 fish now under consideration, this part is but faintly, though distinctly, roughen- 

 ed : " Bloch's gurnard" is also distinguished, not only from this, but every other 

 British species, by having the first dorsal ray the longest ; a circumstance not 

 noticed by Cuvier in his description, which is very minute, and especially insti- 

 tuted for the purpose of distinguishing it from the neighbouring species ; be- 

 tween which and it that circumstance would have formed the most decided cha- 

 racter. The air-bladder, the shape and size of which offer good marks of dis- 

 tinction in the different species of Triglse, is, in this species, 4 inches in length, 

 and 6 inches in circumference, divided anteriorly into two lobes, both conical, but 



one much larger than the other." A continuation of Mr Tempi.eton's catalogue 



of the species of Rayed animals found in Ireland, p. 466 Johnston's illus- 

 trations in British Zoology, being figures and descriptions of Cuvieria Phantapus, 



p. 472, and of Asterias papposa, p- 474 Blyth's further remarks on the 



affinities of the feathered race, and upon the nature of specific distinctions, p.

of the arrival of twenty-nine migratory birds in the neighbourhood of Thetford, 

 Norfolk ; together with some of the scarcer species that have been met with 



during the years 1834, 1835, and 1836, p. 520 Westwood on a congregation 



of moths found in the interior of a tree of the False Acacia, p. 528. 



II. Botany. 



Pamplin on the discovery in Britain of what is supposed to be Gymnadenia 



odoratissima, p. 475 Henslow on the production of sugar- candy in the 



flowers of Rhododendron ponticum ; and on the germination of the seeds of an 

 Acacia by boiling them variously, p. 476. 



Besides these papers there are numerous short notices, of more or less inte-
