DESCRIPTION OF A NEW SHEARWATER FROM THE 
~( HAWAIIAN ISLANDS. 
BY H. W. HENSHAW. 
Puffinus newelli, sp. nov. 
Above, including upper surface of wings and tail, clear and somewhat 
glossy black. Border of under wing-coverts black. Beneath, including 
under tail-coverts, pure white. Maxilla and edge and tip of mandible 
black; rest of maxilla light brown. Tarsus and feet light yellow, but 
black along the outer posterior side of tarsus, the outer toe and half the 
middle toe. Wing, 8.65; tail, 3.75; bill, 1.28; tarsus, 1.80. 
The above is a description of a Shearwater obtained by Mr. M. 
Newell of Hilo (Brother Matthias of the Catholic Brotherhood) 
in Waihee Valley, Island of Ulani, in the spring of 1894, and by 
him recently presented to the author. The sex was not deter- 
mined. The bird was taken from its burrow with several others 
by natives and brought to Mr. Newell alive. The latter saved 
two specimens. One, the type, is in my possession; the other is 
probably still extant and in Honolulu. 
In 1894 the species was numerous enough in the above men- 
tioned locality, but its present status is doubtful, for the mon- 
goose, which is rapidly exterminating the native Puffins elsewhere 
upon the islands, is an inhabitant also of Ulani. 
As this Puffin was quite unknown to me, and as no account of it 
appears in either Rothschild’s or Wilson’s works upon the island 
birds, I sent the specimen to Mr. Ridgway who kindly compared 
it with National Museum material. Mr. Ridgway’s remarks upon 
the specimen are as follows: “ The Pufinus which you sent for 
identification is without doubt a new species. It comes nearest 
to #. auricularis Townsend, of Clarion Island (Revillagigedo 
group, N. W. Mexico), but differs in blacker color of upper parts, 
wholly white malar region, more extensive, more uniform and 
more abruptly white anterior and central under tail-coverts, more 
extensive and ‘solid’ blackish border to under wing-covert region, 
and especially in the very abrupt line of demarkation along sides 
of neck between the black of upper parts and white of under
