Jassa falcata (Montagu). (= Podocerus falcatus (Mont.), in Sars' 

 Crustacea of Norway, vol. iii., p. 594, 1895).* 



A fine male specimen of Jassa falcata [Podocerus falcatus (Mont.) of 

 Sars' Crustacea of Norivay, vol. iii., p. 594] was found in the stomach of 

 a Long-spined Cottus, Gottus scorpius, captured in the Bay of Nigg on 

 June 6th. Another specimen, scarcely mature, was found adhering to 

 a second Cottus scorpius captured in the Bay in July, while several 

 others were obtained in a tow-net gathering collected also in the Bay of 

 Nigg in July. 



Jassa pusilla (G. 0. Sars). 



This was obtained in a tow-net gathering, collected by rowing-boat, in 

 Bay of Nigg, in July; and in another collected by the "Garland " in 45 

 fathoms, off Aberdeen, November 11th, 1900. 



\Microjassa cumhrensis (Stebbing and Eobertson). 



Dredged in 72 fathoms in the Sound of Mull, on March 31st, 1900, 

 aud forwarded to the Laboratory at Bay of Nigg, from the "Garland." 



"f Parajassa pelagica (Leach). [Janassa capillata (Rathke), G. O. Sars.] 



The densely setose character of both pairs of antennae, gives to this 

 species a striking appearance. A few specimens were obtained by Mr. 

 Williamson in some tow-net gatherings which he collected in the Bay of 

 Nigg in July and the beginning of August (1900). Parajassa was also 

 obtained in the stomach of a Pollack caught in the salmon-nets in the 

 Bay of Nigg on the 4th of May previous. 



It may be noted in passing that Mr. A. O. Walker, in the Fourteenth 

 Annual Report of the Liverpool Marine Biology Committee (Trans. 

 L.-pool. Biol. Soc. (1900), p. 16), objects to the use of the name Parajassa 

 for a genus of Amphipods, and states that he fails to see why Jassa of 

 Leach, 1815, should be displaced by a genus of fossil fish founded in 

 1839. But the restoration of Jassa for those amphipods for which Para- 

 jassa has been proposed can only hold good if it has been proved that 

 they do not after all differ generically from such other forms as Jassa 

 (Podocerus) falcata (Mont.). If, on the other hand, it is found that those 

 Amphipods really differ generically from Jassa falcata, and if, for the 

 reason stated, the name Parajassa may not be used for them, it seems to 

 me that some other name than Jassa will require to be substituted, as it 

 can hardly be utilised for two genera, even though they belong to the 

 Amphipoda and are closely allied to each other. 



EricMJionius hunteri (Bate). 



Specimens of EricMhonius hunteri have on one or two occasions been 

 observed in gatherings collected off Aberdeen, but usually in moderately 

 deep water. It occurred in a gathering collected by the " Garland " in 

 40 to 49 fathoms on October 23rd, and in another collected in 45 

 fathoms on November 7th (1900). There appear to be few authentic 

 British records of this species.
