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 with 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. bipunctatus (Zed.) = B. punctatus Rud. 

 1808 = Alyselminthus bipunctatus Zed. 1800, described by P. J. 

 van Beneden 2 from a Turbot and by Rudolphi from Pleuronectes 

 maximus and Gottus scorpius; (ii) B. claviceps (Gze. 1782) Rud. 

 1810, from the intestine of Muraena anguillae, and of Anguilla, 

 vulgaris v. Matz 3 ; (iii) B. neglectus Lonnb. from the alimentary 

 canal of Raniceps niger* ; both (iv) B. laciniatus (Lint.) from the 

 Tarpum, Tarpon atlanticus, and (v) B. occidentalis (Lint.) from 

 a Rock-cod, Sebastodes sp., probably belong to the same sub- 

 family 5 .
