NATURAL HISTORY NOTES FROM TARBERT. 371 



presence of a number of plumose tufts on the 

 abdominal segments ; but these tufts are easily 

 rubbed off in moving the creature about, if one is 

 not very careful. 



Erythrops pygm^a, G. O. Sars. — This little schizo- 

 pod is rather scarce. I have got one or two 

 specimens near Barmore, Lochfyne (a little north of 

 Tarbert), and the tail half of another among some 

 material dredged in East Loch Tarbert. Canon 

 Norman states that this species is new to Britain. 

 I do not know whether the genus is already rexDre- 

 sented in our fauna. 



This little creature, about yjj of an inch long, is 

 really beautiful when alive, having the lovely 

 bright red eyes characteristic of the genus. 



SiRiELLA ARM ATA, M. Eclwards. — I have as yet got 

 only one specimen of this si^ecies, which was dredged 

 in a small bay a little north of the entrance to East 

 Loch Tarbert. It is armed with a long i3ointed 

 rostrum. Canon Norman regards it as j)i"o^^bly 

 identical with My sis Griffithsice, Bell, so named in 

 honour of Mrs. Griffiths, "a lady," Professor Bell 

 says, "to whom natural history is greatly indebted," 

 and from whom he received the only specimens of 

 the species then known. Mrs. Griffiths obtained 

 them at Torquay. 



SiRiELLA Brooki, Nomian. — This also is a some- 

 what rare form. Canon Norman considers it to be 

 new, and has provisionally named it after Mr. G. 

 Brook, F.L.S., Naturalist to the Fishery Board for 

 Scotland. I obtained this sx)ecies in October last 

 year when dredging among Zostera in shallow water 

 in East Loch Tarbert. It was readily distinguished 

 from the numerous forms of the commoner Mysidce, 

 with which it was associated, by its leisurely mode 

 of swimming. It did not jump aside at every little 

 obstruction, as they did, but turned deliberately 

 iiway in another direction.
