100 MR. THOMAS SCOTT ON THE 



Josef Land specimens this joint is subquadrangular, with straight 

 margins, as shown in fig.- 17. The species ia very small — the 

 average length of the specimens is about "56 mm. to '6 mm. 

 (tV ^o -^^ of an inch). The species was moderately frequent in 

 freshwater pools neir Elmwood, Cape Flora. A few of the 

 females carried ova, but a considerable proportion of the speci- 

 mens were more or less immature. 



Aftjr the above remarks on Maraenobiotas had been prepared, 

 I received from the author, Dr. Jules Eichard, an interesting 

 contribution to the literature of the Arctic freshwater fauna, being 

 a report on the Entoraostraca obtained in the freshwatera 

 explored during the recent voyage to the Arctic seas of the 

 steam yacht ' Princesse Alice.' The places visited comprised 

 Lofoten, Spitzbergen, lies Beeren, Hope, de Barents, and 

 Faroe. In this memoir Dr. Richard describes under the name 

 of MesocTira Brucei an harpactid which appears to resemble 

 the Franz- Josef Land form referred to above ; it may not, 

 however, be the same species. 



With regard to the specimens from Franz-Josef Land, the 

 rudimentary form of the mandible-palp, together with the 

 structure of the first and fif ch pairs of thoracic feet, identify 

 them with Mrazek's Ilaraenohiotus ; there may be slight 

 differences in the armature of the swimming-feet, but such 

 diflferences are unimportant in view of the close similarity 

 otherwise.

This species, which is represented iu tlie Franz-Josef Land 

 collection by several specimens, was dredged off East Glacier, 

 Cape Flora, in 30 fathoms, July 21st, 1897. (?) Canthocamptus 

 parvus is a small species that was first described from specinens 

 obtained in the Firth of Forth near Aberlady. The Franz- Josef 

 Land specimens are somewhat larger than those from the Firth 

 of Forth ; there are also one or two other differences, but they 

 are comparatively unimportant. The following is a brief descrip- 

 tion of the Arctic specimens : — 



The antennules in the female are short and sis-joiuted (fig. 19). 

 The antennae have the secondary branches small and two-jointed 

 (fig. 20). The mandible-palp is moderately well developed and
