"Our 'gelinotes' are fat all the year round and of a most delicate taste. Their colour is always of a bright grey, and there is very little difference in plumage between the two sexes. They hide their nests so well that we could not find them out, and consequently did not taste their eggs. They have a red naked area round their eyes, their beaks are straight and pointed, near two and two-fifths inches long, and red also. They cannot fly, their fat makes them too heavy for it. If you offer them anything red, they are so angry they will fly at you to catch it out of your hand, and in the heat of the combat we had an opportunity to take them with ease." Quite extinct. Only known from descriptions and osseous remains. One tibia in the Tring Museum. Habitat: Rodriguez Island. {137} PENNULA DOLE. _Pennula_ Dole, Hawaiian Alman. 1879 p. 54 (Reprint in Ibis 1880 p. 241). I believe that the genus _Pennula_ should be placed near _Porzanula_, but its wings are softer, the rectrices are next to invisible, but can be felt, as they have stiff shafts and are about 13 mm. long, though being entirely hidden by the soft tail-coverts. The tibia is bare for about 7 mm., the metatarsus covered in front with nearly a dozen transverse, very distinct scales, and distinctly reticulated behind. The bill much as in _Poliolimnas_ and _Porzanula_. Two species can be recognized: _Pennula millsi_, with a uniform upper surface, and _Pennula sandwichensis_, with a distinctly spotted upper side. Both forms are now extinct. PENNULA MILLSI DOLE. MOHO OF THE NATIVES. (PLATE 26, FIG. 3.) _Pennula millei_ (misprint for _millsi_) Dole, Hawaiian Almanac 1879 p. 54 (reprint in Ibis 1880 p. 241. "Uplands of Hawaii: named in honour of Mr. Mills, spec. in Mills's Coll., nearly extinct"); Rothsch., Avif. Laysan, etc., p. 241 pl. LXXVI. _Pennula ecaudata_ apud Wilson & Evans, Aves. Hawaii., part V, text and plate. All we know of this bird are the five specimens caught by an old native bird-catcher named Hawelu for the late Mr. Mills of Hawaii. Two of these are now in my Museum, one in Cambridge, and two in the Bishop-Pauahi Museum in Honolulu. There can be no doubt that this bird is now extinct. All recent attempts to find specimens have been futile. Mr. Palmer, whom I sent a specially trained dog, also failed to find even traces of it. It lived formerly in the country between Hilo and the volcano Kilauea, in places where thick grass, _Vaccinium_ and _Dianella_, forms the thickest cover possible. In former times the "Moho" was a dainty on the tables of the Hawaiian kings, but its disappearance is probably due to the introduction of the obnoxious mongoose and to bush fires. {138} PENNULA SANDWICHENSIS (GM.)
