306 Additional remarJcs on the Avifauna of, Sfc. 



by Col. Tytler^ though presented through some mistake in • Mr. 

 Grote's name, were repeatedly examined in life, and one of 

 them after death, by Mr. Gurney, who definitely pronounced 

 them to be hacha. 



This however is not absolutely conclusive as to Elgini being 

 hacha, because there are certainly two species in the island 

 and there mai/ be three. 



I can not get hold of either Daudin^s Traite d^Orn. &c. (II., 

 p. 43) or Levaillant, Ois. d'Afr. I., p. 68, pi. 15, on which 

 Daudin founded his name. 



Horsfield^s F. bido is generally identified with Daudin's hacha, 

 and Horsfield himself concurred in this. Cat. E. I. C.''s Mus., 

 p. 49. Horsfield^s description Lin., Trans. XIII., p. 137, runs 

 as follows : 



"i^. fuscus, capite supra remigihig caudaque nigris ; plumis 

 crista capitis atris hasi alhis ; cauda fascia lata, aTbida, alis siihtus 

 abdomitie crisso criiribiisque albo guttatis. Longitudo 34 ad 36 

 poll. 



This appears to me to agree fairly well with our birds. 

 Swinhoe, Ibis, 1 870, p. 86, and Walden, Ibis, 1873, p. 364, 

 give between them the dimension of eleven specimens of bacha 

 from India (?) Ceylon, Malacca, Java; wing, 14*75 to 16; 

 tail, 9-8 to 11 ; tarsus, 3'35 to 3-87 ; mid toe to root of claw, 

 1-75 to 3. 



These dimensions seem somewhat in excess of ours, but not 

 sufiiciently so, to make me doubt that Elgini'is really bido, Horsf., 

 or {if bacha is certainly = to hido) as it should stand hacha, 

 Dau.d. 



The second species is of a different type, in fact a minature 

 (with some not very important differences) of S. cheela, Lath, 

 It is about the size of bido, with the wing of the female 15. A 

 pale brown beneath, with throat and breast finely barred with 

 darker zig-zag lines ; the tibial plumes much more coarsely and 

 strongly barred ; the abdomen much as cheela. The edge of the 

 wing from the base of the primaries to the carpal joint and the 

 under surface of the wing for an inch inside this margin, 

 between these points, pure white ; bill, brown. 



Length in the flesh, of the female, 34 ; wing 15, against 

 length, 39 ; wing, 31, in the same sex of cheela ; at first I thought 

 this might be Rtttherfordi, Swinhoe, (Ibis, 1870, p. 86,) but 

 this I find has a wing [m. adults) of from 16*5 to I7'75. 



It is not spilogaster, Blyth, which he distinctly says is only 

 slightly smaller than cheela; moreover, I have numerous speci- 

 mens of what both Mr. Blandford and I identify as spilogaster, 

 from Southern and Central India, and Kaipoor, chiefly distin-
