16 Guzae to Whales, Porpotses, and Dolphins. 
Near by is shown a partially fossilised imperfect skull of the 
Southern Black Right-Whale (Balena australis), obtained from a 
superficial formation, two hundred miles from the sea, at Villa 
Constitucion, Rio Parana, Argentina, and presented to the Museum 
by Mr. H. C. Gostling in 1898. 
On the western wall of the building are exhibited several 
blades of the whalebone of the Southern Right-Whale. These 
specimens came from the South Seas, and are described and 
figured in Dr. J. E. Gray’s “ Zoology of the ‘Erebus’ and 
‘Terror’” (1846). They were presented by Messrs. Smith and 
Simmonds. 
This little Whale (Neobalena marginata), the 
only representative of its genus, is confined 
to the southern seas, and is in many respects allied to the 
Right-Whales, which it resembles in the absence of pleats on 
the throat and in the fusion of the cervical vertebrie, although 
it approximates to the Rorquals in the presence of a fin on the 
back. The long, slender, and elastic whalebone is white in colour. 
There are only four digits to each flipper. This Whale attains an 
approximate length of 20 feet, of which about 5 feet is taken up by 
the head. The skeleton exhibited is from New Zealand, and was 
presented by the Wellington Museum in 1876. The species is also 
represented ‘by a coloured cast of the head affixed to the north 
wall of the gallery ; this was modelled from an Australian specimen 
and presented to the Museum by Dr. E. C. Stirling in 1892. 
Pigmy Whale. 
G This species (Lhachianectes glaucus), which 
rey Whale. ei Za 
appears to be restricted to the Pacific coasts of 
North America, where it ranges in summer to the Arctic Ocean, 
and in winter wanders as far south as latitude 20° N., 
differs from the Rorquals in the absence of a back-fin, and 
in the reduction of the pleats in the throat to two, as well as by 
the long scapula, or shoulder-blade. Of the fourteen pairs of ribs, 
the first two on each side are welded together; and the cross- 
shaped sternum, or breast-bone, differs from that of a Rorqual by 
the shortness of its arms and the sharp point formed by the hind 
end. 
This Whale generally grows to a length of from 40 to 44 feet ; 
and its colour varies from mottled grey to black, the whalebone 
being light-coloured and from 14 to 16 inches in length. It is 
essentially a coast-species, frequenting shoal-waters, and has been
