veins by simple or forked nervilles. The two lower i>airs of veins are 

 closer than those above. In a leaf of medium size, the two lower pairs 

 of nerves are 8™"^ distant, while those of the middle are nearly 2^^- The 

 angle of divergence in joining the midrib is open, but the nerves are 

 mnch cnrved upwards in traversing the bhide.

Leaves coriaceous, oval, equally narrowed upwards to a blunt apex 

 and downwards to a short petiole; secondary veins (seven), unequally 

 distant, parallel, except the low^est, which are a little more oblique and 

 ascending higher parallel to the borders; all camptodrome, arched at a 

 distance from the margins, forming a double series of festoons by auas- 

 tomising branches; surface rugose; borders undulate. 



The leaves, according to Ileer, are obtusely dentate on the borders, 

 but part of the margin, near the base of the leaf described above, is 

 destroyed, and Heer's fig. 5 loc. cit. shows from the middle upwards 

 exactly the same undulations as the Alaska specimen. The only differ- 

 ence remarked on the leaf of Alaska is that it is more distinctly narrowed 

 to the petiole. The specimen bears numerous fragments of Taxodium 

 disfiuhum.

The group here under consideration, the so-called "family" Turdida'* 

 has given much trouble to those authors who have tried to arrange the 

 genera naturally, and to define their limits distinctly. I do not intend 

 to give here an analysis of their different essays, but as the last, viz, 

 Mr. Seebohm's in the fifth volume of the "Catalogue of Birds in the 

 British Museum," is very radical and opposed to commonly accepted 



* I am Dot at all conviucetl that tbe groups of the Passercs, generally called lauiilies, 

 are really equivalent to the family groups of the other orders of birds or other verte- 

 hrates ; but as I am, for the present, unable to take up this question, I have con- 

 tented myself with the generally adopted nomenclature.
