 the Faroe Channel measured 3*5 mm. long ; Ksterly records it from Diego, California, 

 3 mm. long. The Southern Ocean species evidently reaches a much greater length 

 (4*5 mm.). 



FAROELLA (WOLFKNOKN). 



In the course of my cruising in the Faroe Channel in 1901 I captured a 

 copepod which differed from any known species, to which I originally gave the name 

 Pfieitdaetidiw multiscrrata, in the paper read at the British Association, 1902. In 1903 

 appeared Bars' supplement, in which he described a new genus, AZtidiojtMi*, which 

 appeared to be the same animal ; and as I had already recognised that this copepod was 

 distinctive from others closely allied (PseuJcetitleu*, Chiridiii*, GaiJhi*), I had created 

 for it a new genus, Fart*-lla. My paper had been in the printers' hands for some time when 

 Professor SOTS' supplement appeared with the description of sKtiiliofuti*. Consequently 

 I do not know to which name priority should be given, nor do 1 feel yet certain that 

 the genus described briefly by Sara is identical with the FnrnfUa ilescriU-d by me in the 

 J. J/. B. AM. of 1904. Certainly the Farotlla of the Antarctic Sea has some dihVrrinT-, 

 and I therefore retain the name for the genus which I originally gave, more especially 

 as Professor Sars, who has examined some Irish specimens, states, as I am informed, 

 that they are not identical with his.

? size 4*3 mm. (cephalothorax 3*3 mm., abdomen 1*0 mm.). The fore-body is 

 therefore over three times as long as the abdomen. The head and first thoracic segment 

 are united, the two last segments of the thorax separate, the anterior segment over twice 

 as long as the four last segments ; the most posterior of these is well defined from the 

 one in front, small, and laterally prolonged into stout spines which are about three- 

 quarters as long as the genital segment In dorsal aspect the head is rather triangular- 

 shaped, and on each side below the level of the posterior antennas, laterally expanded. 

 In the lateral aspect the head is evenly rounded, oval, and with stout two-pointed
