pair, whii'b iirc medium gray (llidgway, ]Nomeiicl, i>I. ii, no. 7), the outer 

 j)air, besides, more or less sprinkled with white in the inner web. 



(3) In ^liJ. hiipoJcHca the slaty color of the top of th(^ head extends 

 considerably further down below andbeliindtiie eyes than in ^3?. hreri- 

 pcs and the line of demarkation between the coloration of the upper 

 and the lower sides is apparently less well detined. 



As a rule, perha])s, the underside in ^-E. hrevipes is more or less 

 sprinkled with dusky, especially on cliest and flanks, but some speci- 

 mens, at least, are fully as white below as ^^\ hypoleuca. 



In addition it may be well to call attention agafn to the white, hairy 

 tilanicnts found in all the three specimens of ^liJ. hrevipes {f<>r<ju<(fus) 

 before me and absent in my specimens of ^E". hypoleuca. Tliis may be 

 a diagnostic character, or it may bo simply seasonal and found in all 

 species. It deserves a fuller investigation, however, than I can give it 

 at present. 



jEstrelata hypoleuca vfus originally introduced by Seebohm into the 

 Japanese avitauna upon tlie strength of specimens collected by Mr. 

 Hoist in the Bonin Islands (Ibis, 1.S90, p. 105). I have now l)efore 

 me another sptM'inicn from the Bonins, collected by Mr. B. !N"akamura 

 in 1892 (Sc. Coll. No. UlM)0), as well as the sp(M'im<'n from the Province 

 of jNlino, Hondo, at the tinie referred to by me as -7v\ leuvoptern. 



MeasurcmentH. 



.Sistrelata longirostris, sp. nov. 



Diagnosis. — Length of nasal tube more than one-fourth the exposed 

 culmen; a white wedge on inner webs of primaries oceu[)ying the basal 

 two-thirds; back, plumbeous; top of head, hind neck, slaty black; feath- 

 ers of rump and upper tail-coverts abruptly white at base; tail-feathers, 

 slate color, white at extreme base, and outer pair strongly sprinkled 

 with white on inner webb; entire undersidepure white, including lining 

 of wing, except a narrow line along the anterior edge, which is white 

 and black mixed. 



Habitat. — North racilic Ocean: I*rovince ot\AIutsu, Japan. 



Type.—iii',. Coll. Mus. Tokyo, Xo. 1583. 



This species differs from all the other true ^JiJstnlata' in its 2)>'oportion- 

 ally long and slender bill, ap])roaching in this respect Coolilaria coolii, 

 in which, however, the nasal tubes are very much shorter. 



As will be seen from the measurements given below, it i.s one of the 

 small species of the genus belonging to the section with large Avhite 

 wedge on theinner web of [)riiuaries. 1 1 eonsecpiently at once differs from
