562 PTEEYLOGRAPHY OF GOATSUCKERS AND OWLS— CLARE, vol.xvii. 



There are fifteen secondaries and twelve retrices, but of tbe latter one 

 bird from the National Museum (iSro. 85253) possessed thirteen.

Nitzsch says of 8. cunicularia that "it has twenty- four reraiges, of 

 which ten are on the hand; the first equals the fifth; the second 

 between the fourth and fifth; the third somewhat longer than the 

 fourth." Since he does not mention the real first primary, it is neces- 

 sary to add one to each of these figures in order, to get the formula as 

 he meant it. Reversing the notatiou, it then becomes 8, 7, 9, 6=10, 5, 

 4, 3, 2, 1, 11, which agrees substantially with what I have given. 

 Although Nitzsch allows the genus only fourteen secondaries, both Dr 

 Shufeldt and I found fifteen. 



Genus GLAUCIDIUM. 



The pterylosis of this genus is very similar to that of Micropallas and 

 .Speotyto, but the infra mandibular region is not at all thickly feathered 

 and there are distinct apteria along the rami of the lower jaw. The 

 upper cervical tract is broader than usual and posteriorly divides so 

 very slightly that the fork is not clearly defined at all, while the dorsal 

 tract extends farther forward than in Asio, although it does not quite 

 reach the end of the cervical. The humeral tracts are not very broad, 

 being narrower than the upper cervical. The femoral tract is well 

 developed and the tarsus is feathered only as far as the somewhat hairy 

 toes. Beneath Glaucidium agrees closely with Asio, although the ven- 

 tral tracts are not quite so clearly marked on the breast. The formula 

 for the primaries is as follows: 7, 6, 8, 5, 4=9, 3, 2, 1, 10, 11. Two of 

 the specimens examined had fourteen and the other two fifteen, second- 

 aries, while there are, as usual, twelve rectrices.

Geuns SYRNIUM. 



The only specimen of this genus which I have examined agrees very 

 well in the general pterylosis of the body with Asio accipitrmus, but dif-
