On -March 2j, \>)i^. Mr. Rnl)ert Cushman Murphy, of the 
r^rooklyn Museum, kindly presented nie with a specimen nf the 
}-oung of Phalacrocorax atriccps gcorgiamis. for the pur])Ose 
of having its anatomical structure examined. This specimen 
bore the number 1620 in Mr. ^lurphy's collection, having been 
taken b}- him when it was but twenty-four hours old at the 
Bar of Isles, South Georgia Island, on December _^o. njiJ. 
It came to me in gauze, dam])ened with the ]3reser\-ati\'e in 
which it had l)een kept, and it was in excellent condition. 
Shortly after its reception I photograi)hed the specimen, natu- 
ral size (Plate I). It was next placed in a bottle containing 
denatured alcohol, where it remained until May 23d, Kji-i-, 
when I again examined it. 
\Mien first received the specimen was of a deep ])lumbeous 
black color, somewhat lighter on the under parts, the feet being 
of a very pale shade of cream-white. 
Below eitlier eve there is a light gray area of abmu the size 
of the eve itself, while the lower mandil:)le, all to its subajjical. 
dark anterior part, is of a slate gray, the ujjper one being 
almost black. At a distance of two millimeters from the tip 
of the latter, in the middle line, there is a small, whitish, cir- 
cular nib, such as is to be observed on the uiijier mandibles of 
young fowls and other birds when thc\" are first hatched. 
A small, white spot indicates the localit\- \\herc the urop\-gial 
gland opens externally, and posterior to it the acute angular 
line, with its apex pointing po.steriorly, where the future rec- 
trices would have made their appearance. Immediately below 
this, in the median line, there is to be observed the rather large 
anal opening, with its prominentlv ele\-ated border or rim. Its 
contour is elliptical, with the major axis transverselv disjxised. 
Posterior to this opening and at a distance of a centimeter in 
the middle line, there is to be found the snmafic iimhilicits. 
which is al)out half the size of the anal aperture, it having a
