In a memoir entitled “ A Description of the Entozoa collected 
by Dr Willey during his sojourn in the Western Pacific” and 
published in Dr Willey’s “Zoological Results,” Part v., Cam- 
bridge, 1900, I described a species of Tape-worm taken from the 
intestine of the sword-fish Histiophorus sp. of the Indian and 
Pacific Oceans. From an examination of the external features 
I came to the conclusion that the cestodes in question were 
examples of the species Bothriocephalus plicatus Rud. which lives 
in the better known sword-fish Xiphias gladius L. In acknow- 
ledging the receipt of a copy of the paper in question Professor 
Lonnberg of Upsala University most courteously pointed out that 
my description did not agree wfith what is known of B. plicatus. 
Dr Liihe in his paper on the Anatomy and Classification of 
the Bothriocephalidae 1 has in fact established a new genus 
Fistulicola under which he places the B. plicatus (Rud.). Fistu- 
licola is grouped in the sub-family Triaenopharinae Liihe, of 
the family Bothriocephalidae, whilst my species, as sections 
which I have recently prepared show, undoubtedly belongs to the 
sub-family Ptychobothriinae Liihe of the same family and to that 
genus which retains the generic name Bothriocephalus. To this 
genus are assigned (i) B. hipunctatus (Zed.) = B. punctatus Rud. 
1808 — Alyselminthus hipunctatus Zed. 1800, described by P. J. 
van Beneden 2 from a Turbot and by Rudolphi from Pleuronectes 
maximus and Coitus scorpius; (ii) B. claviceps (Gze. 1782) Rud. 
1810, from the intestine of Muraena anguillae, and of Anguilla 
vulgaris v. Matz 3 4 ; (iii) B. neglectus Lonnb. from the alimentary 
canal of Raniceps niger' 1 ; both (iv) B. laciniatus (Lint.) from the 
Tarpum, Tarpon atlanticus, and (v) B. occidentalis (Lint.) from 
a Rock-cod, Sehastodes sp., probably belong to the same sub- 
family 5 .
