In the different countries of the world in which I have lived, it has been my lot to see and to study members of the two groups of Kingfishers which Mr. Sharpe calls ‘ fish-eating ” and “ reptilivorous.” Our own 4/ cedo ispida is the most typical example of the former group, while perhaps the great Laughing Jackasses ol Australia are the extreme representatives of the other forest-loving reptile-eating Kingfishers. These two sections, into which the family has been divided by Mr. Bowdler Sharpe in his ‘ Monograph,’ appear to me to rest on natural grounds; but I cannot follow him in his arrangement of some of the intermediate forms, such as the genus Halcyon &c. Nature has here provided us with several groups, each possessing distinctive characters as regards colour &c., which seem to me to afford strong grounds for generic separation. Thus I would follow Lord Tweeddale and Count Salvadori in separating the green Kingfishers as Sauropatis ; and I feel justified in keeping the three species now figured under the one generic heading of Actenoides, believing, as I do, that their peculiar coloration and the character of the feathers point them out as being all closely and generically ailied. I regret that there is nothing recorded of the habits of this fine Kingfisher, which is a native of Malacca, Sumatra, and Borneo. The following careful description is drawn from Mr. Sharpe’s ‘ Monograph,’ with the single alteration that the bird which he describes as ‘“ young” is here considered to be the old female, Mr. Swinhoe (JZ. c.) having procured a properly sexed specimen of the hen bird in this plumage at Penang. ‘Head dull green, with a line of brighter green from above the eye encircling the nape ;_ below this bright green circlet a broad line of black; eyebrow and ear-coverts pale rufous; a line of feathers from base of bill down the sides of the neck deep ultramarine ; back of neck deep sienna, below which the back 1s black ; upper part of the back and scapularies rich ultramarine; lower part of the back very bright cobalt ; quills brown, the inner web pale rufous at the base ; the whole of the wing-coverts and the outer web of the quills rich ultramarine, uniform with the scapularies ; tail blue above, black beneath; under surface of the body rich sienna, the middle of the abdomen white; upper mandible black, fine rich ochreous buff on the under mandible and edge of the upper; feet yellow. Total length 9 inches, culmen 1:9, wing 4°5, tail 2-2, tarsus 0:5, middle toe 0°75. « Female.-—Similar to the adult male, but has the wing-coverts and scapulars spotted with ochre.” In the Plate are represented an adult pair of birds, of the natural size.
