Later, in the Ibis, Dr. Forbes says, "The limb-bones and pelvis correspond so closely to those of _F. newtoni_ that I am not able to separate them. The head of the type is, however, unknown." Professor Milne-Edwards, however, points out numerous differences. In the humerus the sub-trochanterial groove is bigger, and particularly wider than in typical _Fulica_. The iliac grooves are larger than in _Fulica newtoni_, the pelvic knob is more extended, and the sciatic foramen is larger. The first sacral vertebrae are stunted below the median sinus, while in the Mauritius species one observes a very stout one, occupying the four first vertebrae of the pelvis. The feet were also larger and stronger than in the latter. Habitat: Chatham Islands. An almost complete skeleton and numerous bones in the Tring Museum, and an almost complete skeleton in the British Museum. {150} PALAEOLIMNAS NEWTONI (MILNE-EDWARDS). _Poules d'eau_ Sieur D.B., Voyages 1674. _Fulica newtoni_ Milne-Edwards, Ann. Sci. Nat. (5) VIII pp. 194-220, pls. 10-13 (1867). The translation of the Sieur D.B.'s (Abbé Dubois) description is as follows:--"Waterhens which are as large as fowls. They are always black, and have a large white crest on the head." For the anatomical description I must refer my readers to Professor Milne-Edwards. Habitat: Bourbon. Milne-Edwards gives so many details in which _Fulica newtoni_ agrees with _Palaeolimnas chathamensis_ that I feel convinced that the former is not a true _Fulica_, and, until we know its skull and can decide for certain, I think it is best to include it in the genus _Palaeolimnas_. 16 tibiae, 30 metatarsi, 8 humeri, 2 sternums, 4 fragments and an entire pelvis and sacrum, and 3 cervical vertebrae in the Tring Museum. PALAEOLIMNAS PRISCA (HAMILTON). _Fulica prisca_ Hamilton, Trans. N.Z. Inst. XXV, p. 98 (1893). This bird was nearly as large as _Notornis_, but with a very small head and with a frontal shield. It was probably a poor flier, though not flightless, as _Fulica chathamensis_ was. It was smaller than the latter. Measurements, according to Hamilton:-- _prisca_. _newtoni_. _chathamensis_. Femur: Length 78-93 mm. -- 85 mm. Tibio-tarsus: Length 143-162 " 144 mm. 152-163 " Tarso-metatarsus: Length 81-98 " 88 " 96 " Habitat: Middle Island, New Zealand. {151} LEGUATIA SCHLEGEL. Body not larger than that of a goose; wings rather short but still fitted for flight; feathers of the legs reaching down almost to the top of the tarso-metatarsus; toes long and completely free, middle toe almost as long as tarso-metatarsus. Bill with a naked shield reaching back beyond the eye. Height about 6 feet. LEGUATIA GIGANTEA SCHLEGEL. (PLATE 31.)
