sented by the drawings (figs. 1 and 2, Pl. IV.). The body tapers slightly 
towards both ends, and is marked by numerous transverse strize, and thus 
far it agrees with the definition of /. agzlis of Diesing ; there seems, how- 
ever, to be a slight difference in the number of hooks on the proboscis, of 
which there are apparently six in the series instead of three. The hooks 
as shown in the drawing are of moderate size; those surrounding the 
summit of the short truncated proboscis extend more or less outwards, 
while the others, which spring from about the middle and have stout 
gibbous bases, are turned downwards. 
I was at first inclined to ascribe this form to Hchinorhynchus gracilis, 
van Beneden, as the proboscis and its armature resemble somewhat closely 
that author’s figure in Plate V. of his work on the Fishes of the Coasts of 
Belgium,* which species he also obtained in the intestine of Mugil chelo, 
but I scarcely think that van Beneden’s Z. gracilis can be the species of 
that name which Diesing ascribes to Rudolphi, for Diesing’s definition of 
Rudolphi’s Hchinorhynchus gracilis, is as follows :—“ Proboscis cylindrica, 
uncinorum minutorum seriebus, 10-12. Collum nullum. Corpus 
cylindricum retrorsum attenuatum,” t and there is no reference to 
transverse striz. Moreover, the Hchinorhynchus gracilis, Rudolphi, is, 
according to Diesing, found in the intestine of a bird, Coracias garrula, 
Linn, et Gmel. I have, therefore, for the several reasons stated, referred 
our specimens to EHchinorhynchus agilis, Rudolphi, 
SOME ADDITIONAL NOTES, 
(1) ON A LARGE CESTODE FROM THE INTESTINES OF A Common PORPOISE.

This large Cestode was obtained in the intestines of a Common Porpoise, 
Delphinus phoceena, cast ashore in front of the Laboratory at the Bay of 
Nigg. The porpoise had become entangled in the nets belonging to the 
salmon fishers, and being unable to extricate itself had been drowned. 
Dr. Cobbold, who described the Cestode in 1855, and who also obtained 
it in the same species of Cetacean, states that ‘‘ the small intestine of the 
Porpoise was completely choked for the space of eight or nine feet by 
fine tapeworms so closely packed together that the gut presented the 
appearance of a solid cylinder.” These tapeworms, he remarks, were of 
various sizes ; four of them measured respectively from seven to ten feet in 
length, while a fifth was only eighteen inches. 
The Porpoise cast ashore near the Laboratory, and which I had the 
privilege to examine, had the small intestine also crowded with the same 
kind of parasites, and so much so that it seemed to be impossible that any 
matter could pass, yet the Cetacean had the appearance of being in perfect 
health. The removal of the parasites in anything like a complete con- 
dition was very difficult owing to their great length, their being so 
crowded together, the extreme attenuation of the anterior end with its
