Show 1876.] ON THE ANATOMY OF CERTAIN PARROTS. 691 animal, as the lighter grey which prevails between the caudal and dorsal fins might easily become pure white when adult. The figure and description that diverge most are those of Dr. Bright-well. The black colour is described as extending over the whole upper surface of the body in his specimen. This might, however, be an individual variation. On the whole, in the absence of a larger series of specimens for comparison, I am disposed to agree with Dr. Cunningham, and conclude that m y specimen is, like his, a grey Lagenorhynchus albirostris.

Notes on the Anatomy of certain Parrots. By A. H. GARROD, M.A., F.R.S.> Prosector to the Society. [Received June 19, 1876.] Since the publication of m y paper " O n some points in the Anatomy of the Parrots," in the 'Proceedings'of the Society (1874, p. 586), I have had the opportunity of dissecting several species, some of which, from their peculiarities, deserve special note. They are the following:- 1. Dasyptilus pecqueti. It is through the great kindness of Dr. A. B. Meyer that I have had the advantage of being able to dissect this extremely rare bird. Dr. Meyer obtained the specimen in New Guinea, and has preserved it in spirit, entire. He has most liberally allowed me to determine those anatomical points to which I have drawn attention in the paper above referred to. There are two carotid arteries; the left, however, runs superficially as in the Psittacidae (as defined by me). The oil-gland is large, sub-globose and possesses a well-developed tuft of shortish feathers around its orifices. The rectrices are twelve in number. In its myology and osteology it agrees with the Pyrrhurinag in entirely wanting the ambiens muscle, and in having a furcula, which bone is not large or powerful, nor so slender as in the Lories. The orbital ring is incomplete, the eye not being encircled by bone. The femoro-caudal muscle is large; and the semitendinosus with its accessory head are well developed,-in which arrangements it agrees with all the Psittaci. The intestines are 171 inches long, there being no trace of caeca. The liver-lobes are somewhat unequal in size, the left being the smaller. The stomach is small and much like that in the Fruit-eating Parrots generally. The proventriculus forms a dilated sac, of which |
