2. Anous galapagensis. 



(?) Mejralopterus stolidus *, Gould, in Dai-loin's Voy. 'Beayle,^ Birds, 

 p. 146 (1841 : Galapagos Is.). 



(?) Anous stolidus* Sundev. P. Z. S. 1871, p. 125 (Galapagos); 

 Salvin, Tr. Zool. Soc. ix. p. 504 (1877: Galapagos). 



Anous galapagensis, Sharpe, Phil. Tr. clxviii. p. 469 (1879 : Chatham 

 Id., Galapagos) ; Salvin, P. Z. S. 1883, p. 430 (Charles' Id., Gala- 

 pagos) ; Pidffw. Pr. U.S. Nat. Mus. xii. p. 116, no. 44 (1890: 

 Hood & Chatham Is., Galajjagos) ; Stone, Pr. Philad. Acad. 1894, 

 pp. 115-117 (critical). 



Adult ? Sooty brown above and below ; the flight-feathers and 

 tail blacker than the wing-coverts ; bill, tarsi, and toes black, with 

 a livid tinge. Total length 14 inches, culmen 1"8, wing 10*6, tail 6, 

 tarsus O-Do, middle too with claw I'o. 



Immature (type). Similar, but slightly browner; the bill weaker, 

 and shorter in front of the genys. 



Hob. Some islands of the Galapagos Archipelago. 



It was interesting, though not very remarkable, to find that 

 the Galajjagos Islands harboured a sooty form of Noddy as well as 

 a sooty Gull ; but the discovery of the true Anous stolidus (apud 

 Ridgway) on Chatham Island (see supra, p. 139) is a little disquieting 

 for those who wish to believe in the validity of A. galapagensis. 

 I feel tolerably certain that the second of the examples below is 

 not fully adult. 



a. Imm. sk. Dalrymple Rock, Chatham Island, Admiral Kellett & 

 Galapagos. Lieut. Wood [P.]. 



(Type of the species.) 



h. ? Ad. sk. Charles Island, Galapagos, Feb. Sahdn-Godman Coll. 

 (Adml. A. M. Markham). 



10. MICRANOUS. 



Type. 



Micranous, Saunders, Bull. Brit. Orn. Club, 



no. xxiii. p. xix (Jan. 1895) M. tenuii-ostris {Temm.). 



Range. Tropical and Sub-tropical seas. 



Key to the Species. 



a. Lores greyish white ; cheeks grey tenuirostris, p. 144. 



h. Lores deep black ; cheeks deep plumbeous. 

 a'. Darker; nape and shoulders nearly blue- 

 black leucocapillus, p. 145. 



b'. Lighter ; nape, shoulders, and tail dull 



lavender-grey hawaiiensis, p. 148. 



* It is expedient to place a ? against these references because Mr. Ridgway 

 (Pr. U.ts. Nat. Mus. xii. p. 116) states that true A. stolidus was obtained on 

 Dalrjmple Rock, Chatham Island.
