Mcera otlionis (M.-Edw.). 



This species was obtained in a gathering of material dredged by the 

 " Garland " in 72 fathoms in the Sound of Mull, March 31st, and in 

 another gathering collected off Aberdeen in 45 fathoms, November 7th 

 1900. 



Mcera loveni (Bruzelius). (PI. XVIII., figs 27 and 28.) 



A damaged specimen of this species was obtained in a gathering col- 

 lected about fifty miles south-east of Fair Island in about 60 to 65 

 fathoms, October 19th, 1900. Figures 27 and 28 represent the first and 

 second gnathopods of this specimen. 



'Cheirocrates assimilis (Lillejeborg). 



One or two specimens of this species were dredged in 72 fathoms in the 

 Sound of Mull on March 31st, and in 40 to 49 fathoms, off Aberdeen, on 

 October 23rd, 1900. 



LILLJEBORGIID.E. * 



Lilljeborgia tenahani (Bate). 



One or two specimens of this species occurred in the same gathering 

 with the Clieirocrates dredged in the Sound of Mull on March 31st, 1900.

 Photis longicaudata (Bate).

 Island in October and off Aberdeen in 45 fathoms in November, 1900. 



ISCHYROCERID^.f 



Ischyrocerus anguipes, Krbyer. (PI. XVIII., fig. 29.) 



This species was obtained in a tow-net gathering collected in the Bay 

 of Nigg, Aberdeen, on July 17th, by Mr. Williamson, while carrying out 

 some investigations in the Bay by means of a rowing-boat. There does 

 not appear to be any previous authentic records of Ischyrocerus anguipes 

 for Britain. Figure 29, PI. XVIII. , represents one of the second gnathopods 

 of our specimen, which appears to be an adult male. This specimen 

 though somewhat smaller than those from higher latitudes, is in other 

 respects quite characteristic ; the Rev. A. M. Norman has examined the 

 specimen and considers it to be a true Ischyrocerus anguipes. 



Ischyrocerus minutus, Lilljeborg. 



This species occurred in some material collected by the " Garland " at 

 Muckle Ferry, Dornoch Firth, on May 19th, and it was also obtained in 

 the same gathering from Bay of Nigg in which the Ischyrocerus anguipes 

 occurred.
