: 438 THE AMERICAN NATURALIST. [Vor. XXXIV. 
The conclusion of Mr. Jensen's observations is that the hagfish 
fastens its egg by wiry, hair-like appendages to objects on the sea 
bottom. These appendages are fastened to either pole of the egg, 
which is oval in form. Jensen figures a dead stalk of Cellepora, to 
which four eggs are attached.. He gives also several figures of the 
sucker-like anchors (“ thread cells," or “ spider cells "), each with two 
to four lobes in which the hairs which hold the egg terminate. 
A species of hagfish (Zo/istotrema stouti), rather distantly related 
to Myxine, occurs on the Pacific coast, and is abundant in the Bay 
of Monterey, where various features of its structure have been studied 
by several workers in the Hopkins Seaside Laboratory, notably by 
Dr. G. C. Price, Dr. F. M. McFarland, Dr. C. W. Greene, Dr. Bash- 
ford Dean, Dr. Franz Dóflein, and Dr. Howard Ayers. For a long 
time the egg of this species was unknown. At last the Chinese 
fishermen began to bring them in, saying that they got them by press- 
ing the bodies of the females. Many of them were half decomposed 
when received. Later Dr. Dean and Dr. McFarland discovered that 
these eggs were not taken from the females at all, but from the 
stomachs of the males, which accounts for their half-digested condi- 
tion. Nearly all the eggs of hagfish thus far found at Monterey are 
from the stomachs of male fishes. 
Dr. Dean figures one individual in which the clumps of wiry fila- 
ments which hold the egg are caught in the encasing slime of an 
adult animal. ‘The investigations of Mr. Jensen indicate that these 
eggs should be sought on the sea bottom attached to bryozoa or alge. 
Mr. Jensen notes that the Atlantic hagfish has no larval or Ammo- 
coetes stage, such as the lamprey passes through, the young, of six 
centimeters, being similar to the grown fish. In this respect the 
California hagfish agrees with Myxine. DE E 
Waite's Fishes of the Thetis Expedition. — In the Memoirs of 
the Australian Museum, Mr. Edgar R. Waite gives an account of the 
fishes taken by the trawling expedition of H. M. S.-C. Zhetis, Capt. 
C. P. Hildebrand, in the waters about Port Jackson. The collection 
obtained, of which a brief preliminary report has been already pub- 
lished, is a very interesting one, and the paper is one of the most 
valuable contributions yet made to the natural history of Australia. 
The excellent plates are to be especially commended. 
One hundred and seven species were obtained by the Thetis, nine 
of which are new. These are: Dasyatis thetidis, Chimera orgilbyt, 
Anthias pulchellus, Monacanthus setosus, Sebastes (rather Sebastodes)
