REPORT ON THE ENTOZOA.

The nail or thorn-shaped armature of the fifth sucker recalls that of Taenia australis, 
Krabbe, 1 but in the latter they form the apparatus of attachment of the four large 
suckers. The sucKers are also armed with spines in Taenia friedberyen, yon Linstow, 
from Phasianus colchicus i Taenia frontina, Dujardm, from Picus viridis ; and Taenia 
infundibuliformis, G-oeze, from G alius domesticus. 
12. Taenia increscens, n. sp. (PI. II. figs. 13, 14). 
Specimen labelled: “Taenia from H&matopus unicolor , 2 from Hardy Bay, New 
Zealand.” 
Of this form there is only one specimen, which measured 54 mm. in length. The 
scolex is pear-shaped, 0'6 mm. long and 0'4 mm. broad. The apex bears a small pear- 
shaped rostellum, not armed with hooks. The suckers which lie in the anterior third of 
the scolex are spherical, and have a small aperture directed forwards. The so-called 
neck is in comparison very thin and delicate, and measures 0T1 mm. in breadth. At a 
distance of 6 mm. from the scolex the body suddenly expands, increasing both in breadth 
and thickness. Directly behind the scolex the limy bodies in the proglottides begin to 
appear. The first proglottides are 0'06 mm. long and 0‘3 mm. broad; the last are 0'54 
mm. long, 2 '5 mm. broad, and 1'5 mm. thick. In the last proglottides the formation of 
ova has begun, but no mature ova are yet developed. The ova are apparently spherical, 
and have two envelopes, of which the outer measures 0 - 066 mm., and the inner 0'046 
mm., while the oncosphere measures 0'033 mm. 
13. Taenia diomedeae, n. sp. (?). 
Specimen labelled : “ Tseniodes from Stomach of Diomedea brachyura , 3 No. 244, 
28th June 1873, Pacific.” 
The vessel contains seven specimens and several fragments. In none, however, was 
the scolex present. The same vessel contained a specimen of Tetrabothrium torulosum, 
mentioned below. 
No final designation is possible, since the absence of scolex implies the absence of 
diagnostic characteristics. The maximum length was 250 mm.; the anterior proglottides 
are 0‘58 mm. in breadth, and 0T2 mm. in length ; while those furthest back measure 1*9 
by 078 mm. The development of the male reproductive organs begins about 120 mm. 
from the anterior end. The cirri occur on one side. The ova are not yet developed. 
This form is, perhaps, identical with Taenia sulciceps, Baird, 4 which is found in 
Diomedea exulans, but the absence of the scolex leaves this undecided.
