160 DR. JOHN SCOULER. & loose. Tongue fleshy ; its point covered by a semilunar membrane fixed to the lower jaw. This animal is eden- tulous. Xiphias velifer [Xiphias gladiust]. Body somewhat roundish ; becoming very slender before it terminates in the tail, this part is curvated [?]. Gills 5 on each side ; internal ones bilamellar, exterior one single. No swimming bladder. The intestines are very simple, they consist of a stomach which forms almost a cul-de-sac ; & where it narrows & immerges into the small intestine is enveloped by the lobes of the liver. The stomach contained a num- ber of small flying fish & a sepia ; its internal surface has many longitudinal plicse. A short & straight gut goes from the stomach to the anus. Liver about fills the whole abdomen ; at its anterior extremity it is thick & lobulated, towards its caudal it becomes thin. Spleen small & black. 27th. A great many birds of the sub-genus Sula have been flying about the. vessel and several of them have alighted on the rigging.

February 17thi During the very bad weather we have experienced of late, many albatross have been seen & to-day we succeeded in obtaining four of them. In their plumage & internal organisation they differed in no re- spect from those I dissected of[f] Terra del Fuego. It may be proper to notice some mistakes into which Cuvier has fallen, in his Regne Animal with respect to this bird. He says : Us habitent tous les mers Australes, vivent de frofde poissou de mollusques : Regne Animal, p. 1, +517.
