Metridia armatay Boeck. 



Paracalanus hibernicus, Brady and Robertson, Annals and 

 Mag. of Nat. Hist., ser. 4, vol. xii, p. 126, pi. viii, figs. 1-3 

 (1873). 

 Found sparingly in the gatherings taken off Port Erin, 

 Isle of Man. All the specimens obtained were males. 



Pseudocalauus elongatus, Boeck. 



Glausia elongata, Boeck, Oversigt Norges Gopep., p. 10 (1864). 



This species occurs in several of Professor Herdman's 

 tow-net gatherings from Port Erin, Isle of Man. 



Candace truncata (?), Dana. 

 A few specimens belonging to the genus Candace were 

 found among Prof. Herdman's Port Erin gatherings, and 

 were referred to C. truncata , a species new to Britain. The 

 chief distinctive feature of the only known British species 

 C. pectinata appears to be the presence in the male of a long 

 spine at one side only of the last joint of the thorax ; and as 

 all the specimens examined are females, it is just possible 

 they may be C. pectinata ; they do not, however, exhibit the 

 peculiar shape of abdomen figured by Brady as characteristic 

 of the female of C. pectinata. Some more important charac- 

 teristic by which the females of C. pectinata and C. truncata 

 may be satisfactorily distinguished is much wanted.
