APPENDIX. 
Since the earlier parts of this article were printed, a number of 
additional specimens of some of the species have been received. 
Some of these are of importance, as affording additional information 
in regard to the genera and species, and will, therefore, he mentioned 
here. 
I have also received from Professor J. Steenstrup two recent 
pamphlets,* relating to the Ommastreph i dee and Teuthidre, printed 
subsequently to the publication of the pages relating to those families 
in this article. As these refer directly to the genera and species 
herein described, they may well be briefly noticed here. 
Ommastrephes, Sthenoteuthis. Illex. etc. 
Professor Steenstrup, iu the first paper referred to, has given a 
revision of the Ommastrephes-group. He divides the old genus 
Ommastrephes into three genera, viz : I. Illex, which includes 0 . 
illecebrosus, with Coindetii , the closely allied Mediterranean form ; 
II. Todaeodes, which includes only the well-known Ommastrephes 
todarus of the Mediterranean, to which he restores the name sagitta- 
tus Lamarck, which has been otherwise employed by other authors 
during half a century past ; III. OMiiATCSTEEPHEsf (restricted), 
which corresponds exactly with Sthenoteuthis^ previously established 
by me. (These Trans., p 222, February, 1880).

f I can see no necessity for the proposed reformation of the original spelling of this 
word by ehamring it to Ommatostrephes," for usage justifies the elision of a syllable 
in so long a name. The original spelling has been in good use for over forty years. 
f Professor Steenstrup also quotes Cycria Gray, 1849 (ex Leach MSS.), as a syn- 
onym of Ommastrephes as restricted. = Sthenoteuthis. But in reality it was evidently 
intended for a group equivalent to Ommastrephes , in the extended sense, and as a 
complete synonym, never in use, it should be dropped. HyaJoteuthis Gray, if 
used at all. should be used in the limited sense, for a minor group, as originally 
intended.
