tips to the secondaries. Subsequently several names have been proposed, as 

 will be seen by the synonymy adduced ; each based upon the head-markings. 

 The bird has also frequently been described as troile, var.

Fig. IG. — Lomvia californica, (Bry.) Nat. size. 



(No. 17404, Mus. Smiths. A type of the species.) Entirely like iroile, except 

 in the form of the bill. Bill somewhat longer than that of troile, on an 

 average ; deeper at the base, less decnrved towards the tip, the several outlines 

 straighter. Culmen straight to near the tip, then moderately deflexed ; rictus 

 almost perfectly straight in its entire length, the commissural edge of the 

 upper mandilDle toward its base somewhat expanded and everted, as in svarbag, 

 though not to the same degree ; the feathers on the side of the upper mandible 

 not covering the tomial edge until very near the angula oris ; gonys perfectly 

 straight and very long, with a corresponding shortness of the mandibular 

 rami ; the angle at symphysis prominent, acute. " Iris white," (collector's 

 label.) Length 16-00; extent 27-00, (label ;) wing 8-00; tail 2-25; tarsus 

 1-40, middle toe and claw 2-25, outer do. 2-10, inner do. 1-70 ; bill along culmen 

 1-90, along rictus 2-90, along gonys 1.30; its depth at angle of gonys -60, its 

 width opposite base of nostrils -35. 



WiritS plumage. — (No. 46522, Mus. Smiths. Sitka, Nov. 1866.) In this speci- 

 men the bill is shorter (1-75 along culmen) than in the type above described, 

 and the culmen and rictus are more decurved. The peculiar shajie, however, 

 is still preserved, the lower mandible being deep and very prominent at the 

 eminentia symphysis. The bird is probably one of the first winter. The 

 plumage is entirely parallel with that of troile at the corresponding season. 

 The upper parts are fully as dark as in the average of winter specimens of the 

 latter species. The white of the under parts extends to the bill, and along the 

 edge of the under mandible and eyes. Further back it invades the sides of 

 the occiput and nape, where it is separated from the white of the throat Ijy a 

 prominent well defined spur of dark color protruding from the eye.
