XLI. — The Outcome of a South-Sea Voyage *. 

 By L. A. Borradaile. 



Dr. Arthur Willey was engaged on a voyage of research 

 in the South Seas from 1895 to 1897. Since his return his 

 valuable material has been in the hands of specialists, and 

 the results of their labours are to be embodied in a work at 

 present appearing in parts from the Cambridge University 

 Press. The first two of these parts are now before us. 



It is quite clear that, however valuable be the papers by 

 other contributors, the explorer's own communications will 

 form the prominent feature of the series. 



This is amply evident in the first number, in which by far 

 the most important article is the opening one by Dr. Willey 

 on a new species and subgenus of Peripatus from New 

 Britain. In accordance with the territorial nomenclature 

 adopted for many species of the genus, the new form is to be 

 called Peripatus (Paraperipatus) novce-britannice. The male 

 of this creature has 22 pairs of legs and the female, which is 

 larger and more numerous, has 24. There are three spinous 

 pads on each leg, and the generative opening is placed imme- 

 diately behind the last pair. Receptaculaseminis are present 

 in the female, but there are no receptacula ovorum. The 

 eggs are small and without yolk. The accessory glands of 

 the male open to the exterior through a median bulbus imme- 

 diately above the anus. The ductus ejaculatorius is median 

 and short, and spermatophores are not formed.
