PHONA AFFINIS, 71. S.* HeTERURA SYLVAN A, MoTACILLA BOARULA, DrY- 

 MOICA CEINIGER, LaNIUS HaRDWICKII, MoNTICOLA CINCLORHYNCHA, 



Pratincola ferrea, Muscicapula superciliaris, Stoparola MELANOPS, 

 Phylloscopus viridanus, and Turtur ortentalis. 



2. Lt. S. Owen, 19th B. N. I. The skin of a Tern, procured in the 

 Bay of Bengal ; being the young of Onychoprion melanauchen, (Tem.), 

 formerly described by the provisional name Sterna (?) marginata in J". A. S. 

 XV, 373. This specimen is peculiarly interesting, as further confirming, by 

 its coloration, the propriety of arranging the species as an Onychoprion. 

 The head is quite as in O. anasth^etus ; and the dusky hue of other 

 species of the genus is conspicuously shewn on the anterior margin of the 

 wing, and less intensely on the remiges. The structure is altogether that 

 of Onychoprion. 



3. Capt. Berdmore, Scheu Gyen, Pegu. Skin of Capricornis suma- 

 trensis ; and a young living Monkey, apparently of the species Inutjs 



ARCTOIDES. 



4. Capt. S. R. Tickell, Maulmein. A few bird-skins, including Tri- 

 chastoma Abbotti, nobis ; never previously received from so southern 

 a locality. 



5. From the Barrackpore menagerie. A dead Tenasserim Pheasant, 

 Oallophasis lineattjs. 



6. Mons. St. Ives. A pair of small Australian birds, Myzanthe hi- 



RUNDINACEA. 



7- Capt. W. S. Sherwill. Two snakes in spirit, Boa conica and Ly- 



CODON AULICUS. 



* Hesperiphona affinis, nobis. Nearly affined to H. icterioides (Cocco- 

 thrauses icterioides, Vigors). From which the male is distinguished, — 1, by 

 being smaller, the closed wing measuring 4f in. (instead of 5£ in.,) and tail 3£ in. 

 (instead of 3| in.) ; — 2, by the black portion of the plumage being of a deep and 

 shining black, instead of being dull with a distinct ashy tinge ; — and 3, by having 

 black axillaries and yellow tibial feathers, instead of yellow axillaries and black 

 tibials, as in H. icterioides. The females are much more dissimilar : that of 

 H. affinis having the upper parts olive-green, tinged with yellow on the collar 

 and rump, and more brightly on the lower parts ; wings and tail black, the 

 coverts, secondaries and tertiaties broadly margined externally with yellowish 

 olive-green, occupying the whole outer web of the last; crown and ear-coverts ash- 

 coloured, passing to pale grey on the throat. Young male like the adult, but 

 the yellow much less intense. The adult male so nearly resembles that of H. ic- 

 terioides, that its distinctness would scarcely have been suspected, had it not 

 been for the great difference of the other sex.
