distallyj also the tongue of the distal bell is cut ofi rather transversally distally; proximally 

 of the bells these bristles are furnished with short hairs, which are either rather fine or compara- 

 tively coarse; at least some of them are arranged in a few wreaths; sometimes these hairs seem 

 to be almost completely absent. The end comb (fig. 14) consists of about eleven to seventeen 

 teeth of moderate length and strength, decreasing somewhat in length the more proximally they 

 are situated. These teeth are furnished proximally on both sides with a powerful secondary 

 spine and are rather well rounded distally; they are provided on each side with a thin wing-like 

 process, which in most cases, as far as I could see, did not continue as free points (as is the case 

 in Ph. (Ph.) globosa). The cavity dorsally of the end comb is rather deep. Between the end 

 comb and the distal dorsal bristles there are two parallel and somewhat irregular rows, running

longitudinally, of rather short, claviform, smooth chitinous pegs, each row comprising about 

 four or five pegs (sometimes somewhat fewer, broken?). 



Furca (fig. 15) : — This has ten claws, decreasing fairly uniformly in length and strength 

 posteriorly. On the three posterior claws there are no long, stiff ^bristles proximo-medially. 

 Otherwise it is about the same as in Ph. (Ph.) globosa. 



R o d - s h a p e d organ: — This is of quite the same type as in Ph. (Ph.) globosa; its 

 length is a little more than 0,3 mm. 



For the male cf. the description by G. S. BRADY and A. M. Norman, 1896, p. 658. 



Remark: — On account of the incompleteness of the original description of this species 

 I wrote to Professor G. 0. Sars for permission to re-examine the tj^e-specimen. In answer 

 to my request Professor Sars informed me that the type-specimen seemed unfortunately to have 

 been lost, but sent me at the same time, however, two specimens (one male and one female) 

 taken at Vallo, Christiania Fjord, thus near the type-locality which had been determined by 

 him as belonging to this species. The determination of G. 0. Sars' is presumably quite correct. 

 The new description of this species given above is based on this female; of course several other 

 specimens were also taken into account. — The male sent by G. 0. Sars was unfortunately so 

 dirty that it was not suitable for description and reproduction.
