only of mammals, but also of fish, Crustacea, and the lower 
organisms, as Hichini, Polyzoa, Zoophytes, &c. 
In this paper I shall describe two new species—one a 
Shark of the genus Zamna, and the other a Cetacean of the 
family Delphinide, and of the genus Neomeris. 
Taking the Shark first, it is necessary to make mention of 
a species from the Kurrachee harbour, which Dr. Giinther, of 
the British Museum, described in the ‘Annals and Magazine 
of Natural History’ for February 1883, under the name of 
Carcharias Murrayt. It is quite possible that this species 
would be found to occur on the Mekran, Kutch, and Bombay 
coasts also; but at present I am not aware of its distribution 
east or west. ‘T’he several imperfect jaws in the Kurrachee 
Museum from Kutch lead me to believe that the species 
occurs on that coast also. 
The new species of the genus Lamna requires but little 
preface. According to Dr. Giinther (Cat. Fish, Brit. Mus. 
vol. viii.) the genus contains only three species, viz. L. cor- 
nubica, L. Spallanzani, and L. glauca. Of these L. Spallan- 
zant is mentioned by Mr. Day as occurring in the Indian 
Ocean, and a figure of the species is given by him on plate 186 
of his work on the Fishes of India, taken from a drawing by 
Sir Walter Elliot of an example captured at Madras, 
The present species is not LZ. Spallanzani nor any of the 
other described forms, from all of which it differs very mate- 
rially, first in having a greater number of teeth, next in the 
position and shape of the fins, also in the position and short- 
ness of the keel on the sides of the tail ; and, lastly, in having 
a very prominent lateral line or ridge extending from the 
lateral keel of the tail forwards along the entire length of the 
body, rising upwards above the gill-openings and terminating 
immediately behind the eye. 
The species now needs a name, and I venture to associate 
with it that of our veteran ichthyologist, and describe it as 
Lamna Ginthert, sp. nov.
