' Birds of Celebes: Muscicapidae. 
not counting the Lesser Sunda Islands. H. puella is further of interest as an 
inhabitant of both Celebes and Sula. The type of the species is from Sula, 
and the birds from these islands are said by Sharpe to be “a little deeper 
azure-blue than the Celebes birds”, but neither he nor Wallace find them 
separable. Neither are there any apparent differences in those from Peling and 
Banggai, nor are any differences to be seen in specimens from the islands off 
the coast of the Minahassa and in the Gulf of Tomini. 
* 131. HYPOTHYMIS ROWLEYI (A.B.M.). 
Sangi Blue Flycatcher. 
a. Zeocephus rowleyi (1) Meyer, Rowley’s Ornithol. Miscellan. 1878, III, 163; ('2jicl., Isis, 
Dresden 1884, 6. 
Hypothymis rowleyi (1) Sliarpe, Oat. B. IV, 1879, 278; (II) Gould, B. NeAV Guinea II, 
pi. 20 (1882); (3) W. Bias., Ornis 1888, 581. 
Figure and descriptions. Gould II\ Meyer « 1; Sharpe 1. 
Adult. Above dusky China-blue, brightest on supra-loral region, lesser wing-coverts and mantle; 
the quills washed externally with greyer blue; under parts from chin doAvn- 
Avai-ds bluish French-grey, darker on the sides of the breast, paler and washed with 
huff about the anal region; quills and tail beloAV dusky smoke-grey, the inner Avebs 
of the quills whitish. Bill — in dry specimen — blacldsh, under mandible paler; 
feet and claws greyish. Wing 96 mm; tail 92; tarsus 21; bill from nostril 9.5 
(Tabukan, Great Sangi — Nr. 2956, type: Meyer). 
Distribution. Great Sangi (Meyer). 
Remarks. The type of this Flycatcher in the Dresden Museum remains up to the present 
the only specimen on record. It is much larger than H. puella of Celebes: Aving 
96 mm as against 77 maximum; the upper surface is of a much darker blue, and 
tills colour is not carried on to the chin, throat and chest, Avhich are uniform Avith 
the rest of the under surface. It differs, moreover, in the form of the bill from 
H. puellu, tbe nostrils being more deeply sunk in larger caAuties, between which the 
ridge of the culmen stands up more strongly. In this rcsiiect, it appears to be a 
connecting link between Hypothymis and Zeocephus eyanescefus Sharpe of Palawan, 
a species a good deal similar in coloration; but distinguishable by its black lores and 
black fine along the forehead and chin at the base of the bill, by its larger bill and 
longer tail. 
The type of H. rowleyi aauis found by one of Meyer’s huntei’S near the village 
of Tabukan on Great Sangi. Up to the present no Blue Flycatcher has been dis- 
covered on Siao or the other Sangi Islands, and it is probable that the nearest 
relations of H. rowleyi may still be found — there, or elseAvhere. At present its 
nearest affinities appear to be with H. puella of Celebes and Sula, Avhile Stoparola 
panayensis also deserves consideration as an ally. 
Hypothymis manadensis (Q. G.). This species, as Oustalet has shown (Bull. Soc. 
Philom. Paris, Dec. 1877), is from Ncav Guinea — not Celebes. It is the same as 
Mo7iarcha dichrous Gray (cf. Sharpe, Cat. B. IV, 273, 421; Salvadori, Orn. Pap. 
n, 29).
