No. 5. “A fifth was found by Mr. Moore, near Flat Point, east 
coast. A description was sent to Mr. Beetham, M. H. R., who, I 
believe, intends communicating it to this society.” 
From the above descriptions, alone, it is not possible to decide with 
certainty whether these specimens belong to the Architeuthis- group, 
or whether they are more nearly allied to the Onychoteuthis-g roup, like 
Moroteuthis , for the armature of the tentacular arms is not known. 
The broad-lanceolate form of the pen, with a small conical hood at 
the end, would seem to indicate atfinities with Architeuthis , and the 
presence of true suckers, on the sessile arms, and small size of the fins, 
are favorable for that view. Altogether, the descriptions indicate 
that this New Zealand species is related to, and perhaps identical 
with, the one discovered at the Island of St. Paul, and first named by 
M. Velain Architeuthis Mouchezi. It is to be hoped that Mr. Kirk 
will soon give detailed descriptions and figures of the portions in his 
possession.

Plectoteuthis grandis Owen, Descriptions of some new and rare Cephalcpoda, Part 
II.<Trans. Zool. Soc. London, xi, part 5. p. 156, pi. 34, 35, June, 1881. 
Professor Owen, in the paper quoted, has given a somewhat detailed 
description, with figures, of the large cephalopod arm, long preserved 
in the British Museum, and which had previously been pretty fully 
described by Mr. Saville Kent, in 1874, whose description has already 
been quoted by me (see pp. 241, 242). Professor Owen, like Mr. 
Kent, fails to state to which pair of arms the specimen belongs. This 
is a very important omission, for in Architeuthis , as in many other 
genera, the arms belonging to different pairs differ in form and struct- 
ure. The describers of this arm would doubtless have been able to 
ascertain to which pair it belonged by a direct comparison with the 
arms of Ommastrephes , or any other related form. 
For this arm, Professor Owen endeavors to establish a new genus 
and species ( Plectoteuthis grandis). The genus is based mainly on 
the fact that there is a marginal crest along each outer angle, and a 
narrow protective membrane along each side of the sucker-bearing 
face. These peculiarities are precisely those seen in the ventral arms 
of Architeuthis , and have already been described by me in former 
articles, and in this report (see pp. 214, 261, 262), both as found in 
A. Harveyi and A. princeps. Similar membranes or crests are found
