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 Norway, vol. iii., p. 594] was found in the stomach of 
a Long-spined Cottus, Cottus 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. O. 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. 
TMicrajassa cumbrensis (Stebbing and Robertson). 
Dredged in 72 fathoms in the Sound of Mull, on March 31st, 1900, 
and forwarded to the Laboratory at Bay of Nigg, from the ‘ Garland.” 
TParajassa pelagica (Leach). [Janassa capillata (Rathke), G. O. Sars. ] 
The densely setose character of both pairs of antenne, 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 Pava- 
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 fulcata, 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. 
Erichthonius hunteri (Bate). 
Specimeus of Hrichthonius huntert have on one or two occasious 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.
