F. ERNEST WEISS. 
I was not able to make out any commissure connecting the 
stellate ganglia, which was, perhaps, owing to my not being 
able to dissect to the uttermost this valuable specimen which 
was to be remounted for the Museum. 
The pallial nerve is given off from the stellate ganglion itself. 
Doratopsis vermicularis (Riippell), de Rochebrune, 
[Loligopsis vermicularis (Verany)]. 
Plate IX. 
The specimen studied by me was obtained at Messina, and 
was presented to Professor Lankester two years ago by Pro- 
fessor Kleinenberg, of the University of Messina, together with 
several rare Cephalopoda. 
From the excellent drawings of this specimen made by Miss 
Stone, several interesting points can be made out which are 
not given by Verany in his PI. 28, a, b. 
The general proportions of the specimen I examined, which 
was considerably smaller than the one described by Verany, 
differ considerably from those of the latter. 
Compared with Miss Stone's drawings, which are very accu- 
rate, Verany figures the fourth pair of arms too short and 
stout, and the three other pairs too long. The region between 
the base of the arms and the eyes is too long, the neck too 
thin, and the spine at the end of the body too long in fig. a. 
In fig. b the spine is too broad, its length being about right. 
In neither figures does he show what I shall presently 
describe as the stellate organs and the olfactory organs 
respectively. 
The order of the arms is as in Chiroteuthis, 4, 3, 2, 1, and 
the tentacles exceed the fourth pair in length. The arms, 
1, 2, and 3 are very short compared to the size of the body, 
with no dorsal webs or fins, and bear two rows of small 
sessile suckers. 
The fourth pair of arms are enormously large compared to 
the others, more transparent and thicker than the tentacular 
arms. They possess only one row of suckers disposed at 
greater intervals.
