Gasco has given figures of many of the vertebrie of the Taranto (Italy) skele- 
ton (47, pls. 8, 5, 7, 8), in which the outlines are taken from photographs. These 
figures I have compared with the Long Island (N. Y.) skeleton in the National 
Museum, No. 28077, and find a most complete agreement, except in one or two 
cases. In the figure of the 4th lumbar of the Taranto skeleton (vertebra No. 24) 
the anterior zygopophysis is much smaller than in the Long Island skeleton, and 
the posterior margin of the base of the neural arch is much more curved. In the 
side view of the Ist lumbar of the Taranto whale (vertebra No. 21) the transverse 
process is represented as having a peculiar shape and direction which is not evident 
in the front view of the same vertebra, and is not found in the Long Island skele- 
ton. ‘The sixth caudal (vert. No. 39) of the Taranto skeleton is represented as 
having only a shallow emargination inferiorly, while in the Long Island and other 
specimens the emargination is very deep and the anterior and posterior margins 
come close together, foreshadowing the formation of the foramen which is found in 
the posterior caudals. There is every probability that this figure is incorrect, or 
that the vertebra is imperfect below. All the vertebre of the Taranto skeleton 
are figured without the epiphyses, and hence appear thinner than they otherwise 
would.
