IsuRUS, Rafinesque (1810). 
16. I. GLAUCUS, M. & H., s]}. Common in the Port Jackson dis- 
trict, and much dreaded by the fishermen, who call it the 
“ Blue Pointei’,” and credit it with being the boldest of all 
the larger sharks which frequent our coast. Instances of 
its leaving the marks of its teeth on an oar or the timbers 
of a boat are said to be not uncommon, and even so far 
does it carry its boldness that Dr. Ramsay has told me of 
a case of its striking and piercing the timbers of a boat so 
far as to be unable to withdraw its snout ; it is however 
with no sinister design on the crew that these occurrences 
take place, but simply due to the reckless eagerness with 
which it pursues hooked fish. Touching the adoption of 
the name Isurus, I feel bound for reasons given above to 
adhere to the oldest name subsequent to 1766, and since 
Rafinesque founded this genus for the reception of the 
Mediterranean species in 1810, seven years previous to 
Cuvier’s Lainna, and at the least twenty-three to that of 
Agassiz’s Oxyrhina, I can have no hesitation in making my 
choice of a name. The spiiacles are present, but in a 
rudimentary condition, and are situated rather nearer to 
the eye than to the first gill-opening.

Mr. Allport in his MS. list of Tasmanian fishes includes the 
above species, but I am inclined to think that on a re- 
examination of fresh specimens it will be found necessary 
to change the nomenclature of the Tasmanian species of 
Iannis.
