Colymbus holboelli, Baird, Brewer, & Ridgway, Water-Birds N. Amer. ii. p. 428 (Eastern Siberia and south to Japan). a. Vladivostok, October 1879. b, c. Olga Bay, September 1879. Specimen a is not in perfect plumage, the feathers on the neck being partly red and partly grey ; b has hardly any traces of rufous, and indeed looks like a young bird, its underparts are white. Specimen c is fully adult, and bears the nearly perfect nuptial plumage : grey cheeks, red neck, and darkish underparts. This species differs from P. griseigena in being notably a larger bird. It also inhabits North America, including Greenland, whence came the types described by Reinhardt. It has escaped the notice of Pere David. REPTILIA. I. TRIGONOCEPHALUS BLOMHOFFII, Boie. ?

Fusan, August 7th, 1880. The first two are larger and much finer specimens, the two from Corea are not only smaller but less well preserved ; all are in spirit. The dark markings on the upper parts of the two Olga Bay specimens are most conspicuous and have a greenish tinge. From the note on the label attached to the bottle which contained them, it would appear that they were caught in the river. I cannot divest myself of the idea that this species and T. halys are one and the same; in that case the latter name has the priority ; but I have no western, or rather Caspian, specimens to compare with my eastern ones. These agree perfectly with Schegel's description and plate of Japanese specimens. 2. TROPIDONOTUS TIGRINUS, Boie. Tropidonotus tigrinus, Boie in Isis, 1826, p. 206 (Japan); Schleg. Faun.
