to Bermuda, according to the season ; and he states that he cannot 
find any sufficient difference in the skeleton of the Cape specimen 
in the Paris Museum to separate it as a species from the Green- 
land example. A young female, thirty- five feet long, the pectorals 
measuring ten feet, was obtained in the estuary of the Dee in 1863, 
and its skeleton is now exhibited in Liverpool. The stomach con- 
tained only shrimps. There is a very fine and complete skeleton, 
forty- six feet in length, of an adult individual in the museum 
at Brussels. Dr. Gray, however, regards the Bermuda Hump- 
back as distinct, and terms it M. americana. One is described as 
measuring eighty- eight feet in length, with the flippers twenty- 
six feet long, and the tail flukes twenty-three feet broad. The 
Cape Hump-back is the Poescopia Lalandii of Dr. Gray ; and his 
Esehrichtius robustus is a remarkable northern species, of which 
not much is known. A skeleton of it was found in Denmark at a 
depth of two to four feet below the surface of the ground, about 
840 feet from the present sea-beach, and about twelve to fifteen 
feet above the level of the sea. Other Hunch-backs are indicated 
by Dr. Gray, as Megaptera novazelandim, M. (?) Burmeisteri , from 
the coast of Buenos Ayres, and M. Kuzira , from that of J apan. 
The numerous Borquals fell under Dr. Gray’s subfamilies Phy- 
salince and Balcenopterince , which do not differ much from each 
other. To his genus Physalus he refers, — 1. P. antiquorum, the 
ordinary Great ^Northern Rorqual ; 2. P. Duguidii, also northern; 
3. P. Sibbaldii (afterwards identified with Cuvierus latirostris, but 
the specific name Sibbaldii being retained; a valuable memoir 
upon which has been published by Dr. J. Reinhardt),* again 
northern ; these three are now tolerably well known, but the 
following are much less so — 4. P. (?) australis, Falkland Islands ; 
5. P. brasiliensis, from near Bahia; 6. P (?) fasciatus , from 
the coast of Peru; 7. P. indicus ; 8. P. (?) iwasi, Japanese seas; 
9. P. antarcticus, from those of Hew Zealand ; 10. P. Grayi, which 
has to be added, from the Australian colony of Victoria, where it 
has been described by Professor McCay, an example of it having 
been there stranded that measured ninety feet in length, f Other 
species, detached from Physalus, are Benedenia Knoxii, obtained on 
the coast of Wales ; Cuvierus Sibbaldii, already noticed ; Sibbaldius
