EIGHTEEN NEW SPECIES AND ONE NEW GENUS OF BIRDS 

 FROM EASTERN ASIA AND THE AI^EUTIAN ISLANDS. 



By Austin PI. Clark, 



Of tlie United States Bureau of Fisheries. 



This paper is based mainly on a collection of birds 'made by the 

 late Mr. P. L. Joiiy during; a residence of over three years in Korea. 

 It contains 554 excellent skins, mainly from Fusan, Chemulpo, Seoul, 

 and Tsushima, with a few from Gensan, and is much the most 

 important collection ever made in that country. Many of the spe- 

 cies were not known from Korea at the time the collection was made, 

 but most of these have since been recorded. There are a few which, 

 although commonly supposed to be accidental in Korea, are repre- 

 sented by a considerable series, showing them to be of regular occur- 

 rence, at least during the migrations. Mr. Jouy was engaged in 

 working up the collection at the time of his death, on March 22, 1894; 

 but aside from notices of a few species in Dr. Leonhard Stejneger's 

 articles on the avifauna of Japan, nothing has ever been published 

 in regard to it. 



In the preparation of a paper on the ornithological results of the 

 recent cruise of the United States Fisheries steamer Alhatross in the 

 north and northwest Pacific and the Japanese seas, I have courte- 

 ously been permitted to make use of this collection, which is most 

 interesting in bringing out the relationship of the avifaima of Japan 

 to that of K'orea. 



TISA« Clark, new genus. 



Medium sized, semiterrestrial finches with the bill rather large, 

 moderately stout, and conical. 



Bill about half length of head, conical, the depth at base greater 

 than its width at the same point, the distance from nostril to tip of 

 maxilla equaling the gonys in length, and also equaling the distance 

 from inferior corner of mandible to base of culmen. Culmen and 

 gonys nearly straight, the former slightly decurved at tip; tomia of 

 the maxilla nearly straight, with a small notch near the tip; nasal 



a From the Russian iiTHn;a (signifying bird).
