This species appears to be allied in a certain degree to Pro- 

 cellaria rostrata, Peale, having a robust bill as in that species, 

 although not so high at the base, being instead broader than 

 high ; moreover, in our species the frontal feathers advance 

 abruptly as far as the base of the nasal tubes. It differs also 

 in the darker and blacker colour of the upper parts, the edges 

 of each feather in certain lights being distinctly lighter, and 

 wanting completely that sepia-brown tint so characteristic of 

 P. rostrata {cf. Cassin, Orn. U. S. Expl. Exp. 1858, p. 412, pi. 

 41). Our species, besides, has a white throat, and the forehead 

 washed with silky white, which extends laterally and posteriorly 

 as far as over the eyes ; this is an important diagnostic character : 

 besides this last feature, it differs from P. incerta, Schlegel, in 

 its much darker upper parts, in its well-marked jugular band, in 

 its white under tail-coverts, and in its smaller dimensions. 



In the specific name given to our species, we wish to com- 

 memorate that of the first Italian man-of-war which has cir- 

 cumnavigated the globe.

" I found this species pretty common near Trinidad Island, 

 in the South Atlantic, in lat. 20° S. or thereabouts. On the 23rd 

 of January, 1868, as we lay becalmed about eight miles off the 

 island, many specimens were shot; unfortunately, believing it a 

 well-known species, I had only two skins prepared. Bill black, 

 tarsi and basal portion of the toes and membranes flesh-colour, 

 the distal parts being black; irides brown." — H. H. G.
