■ BIRDS OF TENASSERIJT. 341 



"You may also be interested in hearing- that Lucustella dorice, 

 (Calamodyta ' dor ice of Salvadori), and probably also Locustella 

 minor of David aud O us tele t, and possibly Lusciniopsis japonica 

 of Cassin, are all synonyms of L. certJiiola." 



We may certaiuly agree that L. dorice, Salvador! (wrongly 

 recently identified with L. lanceolata) , is synonymous with 

 L. rubescens, Blyth, at least if Mr. Sharpe has correctly 

 figured dorice, Ibis, 1876, pi. II, for that plate corresponds well 

 with a specimen of rubescens, that I have from Jerdon, labelled 

 by Blytli himself. 



This bird is certainly not rare during the cold season in 

 Lower Bengal, and } r et I know scarcely any species, included 

 in our list, of which it is more difficult to procure specimens. 



This species bears a strong superficial resemblance on its 

 upper surface to C. schoenobanus of Europe, but is distinguished 

 at once by (amongst other things) its much longer and more Acro- 

 cephaline bill, its larger and less Acroceph aline first primary, and 

 (in all the very few specimens I have examined) by the pure white 

 of the central portions of the lower breast and upper abdomen. 

 I should expect this species to occur in Tenasserim, but I have 

 not as yet seen any specimens thence. 



Mr. Seebohm continues : — 



" When I was in St. Petersburg, I examined Middendoi'f s 

 types of Locustella oclwtensis, and found that they were young 

 birds of L. subcerthiola of Swinhoe, the adult birds having 

 been mistaken by Middendorf for L. certhiola, Pallas. The 

 name L. ochoiensis will, therefore, stand upon the young bird, 

 and L. subcerthiola, Swinhoe, and L. certhiola, Midd. nee Pall., 

 are synonyms. To these sj-nonyms we must, in my opinion, 

 add Arundinax blackenstoni, Swinhoe, which appears to me to 

 be immature oclwtensis, exactly like Middendorf s types. 



" A still more interesting identification, which I venture to 

 suggest, is that A crocephalus fasciolatus, Gray, the Calamoherpe 

 subflavescens, of Elliot, is the immature bird of Acrocephalus 

 insularis of Wallace, the Calamodyta fumigata of Swinhoe.'"' 



To this latter identification I should prima facie demur, though 

 Mr. Seebohm may be right. I have two specimens of fasciola- 

 tus frcm Batchian, two of insularis from Chefoo, and one of 

 fumigata from Amoy. Insularis and fumigata are obviously 

 identical, as v«as long since first pointed out by Mr. Swinhoe 

 himself, but not so, it seems to me, fasciolatus. 



I do not lay much stress on the difference in coloring, though 

 this is very marked ; the gi'ey aud brown of the lower surface 

 of insularis, the olive and 3 r ellow of that of fasciolatus, &c. ; 

 these might be due, not perhaps so much to age as to season, my 

 insularis having all three been procured in Maj T and June, my 

 fasciolatus in January ; but there are marked structural differ-
