Small Alcidae (wing 112-143 mm.) with bill small and narrow, 

 the exposed culmen not longer (usually shorter) than tarsus; nostril 

 broadly oval, pyriform or triangular, near anterior end of the mostly 

 feathered nasal fossa, tarsus much shorter than middle toe without 

 claw, recticulate in front, and with 14 rectrices. 



Bill small and narrow, the exposed culmen never longer (usually 

 shorter) than tarsus, its greatest depth little if any more (usually 

 much less than) half the length of exposed culmen, and decidedly 

 greater than its width at latero-frontal antife; culmen regularly 

 (sometmies rather strongly) convex from near base; gonys decidedly 

 to much shorter than distance from anterior end of nasal fossa to 

 tip of maxilla, nearly straight, ascending terminally, its basal angle 

 more or less prominent; maxillary tomium faintly convex proxi- 

 mally, faintly concave distally, distinctly notched sub terminally; 

 mandibular tomium nearly straight, distinctly notched near tip; 

 nostril broadly oval, pyriform or triangular, in anterior portion of 

 nasal fossa, in contact posteriorly and for posterior half of upper 

 margin with loral or latero-frontal feathering, the latter very 

 slightly if at all divided or indented at base of culmen; mandibular 

 rami mostly if not wholly feathered except along upper margin. 

 Wing small, with longest primary (outermost) equal to slightly 

 more than half the length of wing. Tail about one-fourth as long 

 as wing (or very slightly more), slightly rounded, the rectrices 

 relatively broad, 14 in number. Tarsus much shorter than middle 

 toe without claw (only as long as first two phalanges of middle toe, 

 or even shghtly shorter), the acrotarsium reticulate; outer toe
