p. 338 Skeleton alone wd have been thought a fish: a interesting combination of Osseous & cartilaginous types

p. 339. Extremities in an Embryonic state of simplicity without digits.

p. 339. Muscles of Perennika Ac. & of young Batrachians approach in some respects muscles of fish

p. 340 Brain of Lep: approaches nearer to Perennibranchia than to any fish, & deviates from both divisions of Fish.

p. 347.— Respiration organs of Lep. approach in filamentary condition to Perennibranchiate.; & intermediate between, or rather in one respect like Plagiostomus one of Cartilaginous & one in another respect like Osseous Fishes

p. 349. Female gen: system is as high as in Plagiostomous fishes, but in other points more resemble those in the Axolotl Perenn Amphiuma Curia, thinks not Perennib. & Siren

p. 350 Siren is most fish-like of Amphibians, but it has two auricles, whilst Fish have only one

— Lepidosiren has one auricle, but so has the Proteus a Perennibra Lep: is not fish from arrangement of branchia for these resemble those of young Batrachians

[81v]

351. Nor is Lep. a fish from spiral intestine because Ichthyosaurus probably had same

The perennibran Batra. have the doubly concave vertebra, which is most eminent osseous character of Fish They have same organs of hearing

{no line can be drawn between Fish & Amphibians from generative system

The organ of smell as final & only character; in every fish a short sac. in every Reptile open also to mouth.— in Lep: it is in former case

Admis this is too physiologically unimportant, if not joined with concurrence of icthyic characters in so many parts of organization —

353 Opposite or Reptile character of Lep: lies in the lung-like development of swim-bladder; but several Sauroïd fish have this same character; & to different genera of Sauroïd fish it approaches in form of entrance entrance of ductus pneumaticus, & in form of swim-bladder, & in straightness, shortness & valve of intestine.—

Also some alliance with one Siluroid fishes (not Plagiostomous)

p. 355. Finally Lep. forms a family connecting Cartilaginous fishes with the Sauroid genera Polypterus & Lepidosteus
