those who had the good fortune to have an intimate personal 

 knowledge of himself and of his investigations in his study 

 who can at all realize the indefatigable perseverance, the 

 marvellous lahoriousness, the most strict conscientiousness, 

 and withal the deep humility of his great mind. Alas ! that 

 both my dear friends should have been taken, and tlieir joint 

 monograph on the British Tunicata remain incomplete ! At 

 the time of Mr. Alder's death his part was finished, which 

 related to the description and illustration of the generic and 

 specific forms ; and the last years of Albany Hancock's life 

 were devoted chiefly to the elaboration of the structure of this 

 most anomalous and higlily interesting class. A large portion 

 of the knowledge thus acquired has unfortunately died with 

 him ; but we yet hope to see such portion of the anatomy 

 and physiology as relates to the simple Ascidians, together 

 with a monograph of all the species, published under the 

 kindly editorship and careful supervising hand of the man 

 most competent to undertake it — Professor Huxley. 



LXV. — Descriptions of supposed new Birds from the Kaga 

 Hills and Eastern Assam. By Lieut.-Col. H. H. GODWIN- 

 AUSTEN, F.Z.S. &c. 



Turdinus nagaensis^ n. sp. 



Above dark umber-brown throughout, with no streaking on 

 the feathers of the head. Beneath the same coloui", but much 

 paler, with a slight rusty tint shading into and adjacent to 

 the dull whitish centre of breast ; chin also whitish. 



Irides dark brown ; legs and feet light sienna-grey. 



Length about 5*7 inches, wing 2"2, tail 2*2, tarsus 0*90, 

 bill at front 0"oO, mid toe and claw 072, hind toe 0*35, 

 claw^ 0'3. 



This species is very distinct from T. garoensis in its deeper 

 umber coloration and smaller size; particularly is this the case 

 in the size of the legs, feet, and the hind claw. Mr. A. W. 

 Chennell, of the Topographical Survey, obtained this bird in the 

 Eastern Naga hills. 



Staphida plumheiceps^ n. sp. 



Head ash-grey, purer behind ; feathers narrowly edged 

 paler. Back ])ale olive-brown, a few feathers ])ale-shafted. 

 Wings umber-brown. Taildarkor,tho four outer feathers tipped
