21. p. 23 it was being pushed into position for the camera it usually turned a bit at to stick instead of avoiding it. In a pool in the river it first descends deeply. Now lay in the water floats quite high in it (perhaps due to quantity of air in fur); afterwards it swims steadily and dives a number of times to the bottom of the quite shallow pool in which it was first tried. In a deeper pool it refused to dive, being tired perhaps. The external anatomy of the animal needs little noting. The head is very flat or type and the eyes small (6 mm.) from corner to corner, vibrissae long & prominent, tips upper lips straight and transverse marked overhanging the mouth; median cleft of upper lip pronounced and deep, rhinarium bare only between the nostrils where openings are turned upward and backward— thus remaining above water when most of the head is submerged. Ears rather small lacking external features. The fureta of the back carries down the shoulder and later side of fore-arm into the outer dorsal side of the head and covers the 5th digit and the base of its 4th. No webbing on fore feet (mm. surrounding); hind feet with half web between D 2+3 and 3+4, Plantar surface with usual tuberculate surface and reduced pads. Testes very large. Tail with long dark hair, 4th the last 100 mm. with the hairs white. Longest digit of h.ft the 4th. Thumb of four feet with claw approaching nail-like form. When skinning the specimen it was found that the infra-orbital branch of the Trigeminal nerve follows the large infra-orbital foramen and extends forward as a number of nerve branches to innervate the turgid upper lip region in which all the large vibrissae take their beginning. The palatal ridges are as below: The tibia and fibula are fused; the radius and ulna free. The tail will not "pull" but 1st molar surface must be split and skinned, except at the very tip. The two molar teeth are relatively narrow, as the species is probably esox (or perhaps beccarii or naucraus). This afternoon Kelly + I finished rough-plotting our map of the trip into the mountains. It indicates a number of minor changes in Champion's map & shows the route followed by us fairly well. Shortly, one of my boys brought me in a male spotted eunuch just now (6 p.m.). It was shot a couple of miles south of here. It is a fine specimen in excellent pelage.
