The classification I have adopted is that I have used in my 
own cabinet. It is in the main based upon that of Woodward 
by far the best ever published. Some of my innovations may 
seem hazardous, but I have never departed from my model 
without the most substantial reasons. The systems devised by 
various concliological writers seem to be founded on the most 
arbitrary and artificial characters and I have found myself unable 
to adopt them. And although the arrangement of my list may 
not in every point meet with the approval of all conchologists it 
is the best my information allows me to frame, and I believe it 
is in some respects an improvement upon many in use. 
Order Octopoda. 
Octopus Cuvier. 
1. O. americantts Orb. 
O. vulgaris, D’Orbigny, Moll. Cuba, vol. i, p. 11, pi. 1, f. 1. 
I cannot assert that there exist any characters sufficiently 
marked for the separation of this West Indian Octopus from the 
widely-distributed form called 0. vulgaris. On his plate quoted 
above D Orbigny calls this var. americanus but in the text he 
does not give that name, but merely points out the differences. 
Order Decapoda. 
Loligo Lamarck. 
2. L. plei Blainv. D’Orb. Moll. Cuba, vol. i, p. 42. 
Sepioteutiiis Fdrussac. 
3. sepioicleo, Blainv. D’Orb. Mol]. Cuba, vol. i, p. 34. 
It is scarcely necessary to make any remark upon these 
species of Kephalopoda, which are not uncommonly taken by 
the fishermen in the Gulf. They are used as food. 
Spirula Lamarck.
