WHITE-BELLIED STORM-PETREL. 21 
It recalls Pealea lineata Peale, but as the basal phalanx of the middle toe is longer 
than the remaining joints and claw, it must be classed in the genus F’regetta. Its 
measurements are: culmen (exp.) 14, wing (worn) 155, tarsus 37, and middle toe 
without claw 21 mm. 
Genus FREGETTORNIS. 
Fregettornis Mathews, Birds Austr., Vol. II., pt. 1, p. 31, May 30th, 1912. Type (by original 
designation): Procellaria grallaria Vieillot. 
Small Storm-Petrels with short bills, long wings, long square tail, long legs and 
small feet. The bill has the tubular nostrils semi-erect, the unguis weak but strongly 
hooked, the laterals not much diverging ; the unguis of the lower mandible is weak, 
the interramal space narrow and feathered. The wing is very long and the wing 
formula as before. The tail is square and about half the length of the wing, the 
feathers broad. The legs are long with tibia exposed, but rather short for this 
series ; the toes are comparatively short with very short broad claws, and although 
the usual proportions obtain, the toes all appear almost subequal. The hind-toe 
is a mere speck, and the anterior toes fully webbed. 
Coloration as in preceding genus, but also unicolour phases occur.

Lord Howe Island.

Adult female (type of F. innominatus Mathews).—Dark blackish-brown on the 
head and neck ; mantle, back and scapulars blackish-brown, the feathers narrowly 
margined with white; median wing-coverts greyish-brown ; lesser wing-coverts, 
bastard-wing, primary-coverts and quills black ; ramp and upper tail-coverts white,

Egg.—Clutch, one; dull white, slightly spotted at the larger end with reddish- 
brown. Dimensions 33.5 by 25 mm. 
Breeding-season.— January. (Lord Howe Island.)

Island subspecies but the South American. 
Famiry PROCELLARIIDA. 
This may be a composite family, including as at present constituted the Shear- 
waters, Fulmars, Prions and the Giant Petrel. The Shearwaters and Fulmars
