bluntly roumlecl and furnished with one moderately loni^ and 

 a few minute scttii ; the basal joint is also frin^etl with small 

 setaj round the outer margin and end ; 8econ<lary joint sub- 

 eylindrical and provided with five spiniform and coarsely 

 ]ilumose terminal setie (Hi^. 20). (Jaudal stylets very short.

 Forth ; rare. 



liemarks. This species is considerably larger than either of 

 the other two I'.seuaoiocsticoodias, and hence the specific name 

 we have adopted for it ; it differs from both, particularly in 

 the structure of the anterior antennae and in the form of the 

 filth pair of swimming-feet ; the inner brandies of the first 

 ])air are also observed to be distinctly more elongate, even 

 without dissection. All the three species closely resemble 

 ]]'eii(ivoodia nohdis (Baird) in general appearance, and may, 

 on that account, have been overlooked by students of the 

 Copepoda.

We have much pleasure in recording this curious species 

 for the first time for Britain. It was obtained in brackish 

 ])Ools just beyond high-water mark of ordinary spring tides, 

 at the head of West Loch Tarbert, ArgylLshire; several 

 specimens were obtained. These West Loch Tarbert speci- 

 mens agree in every particular with Dr. Poppe's description 

 and figures, exce[)t that the outer branches of the first pair of 

 swimming-feet are three- instead of two-jointed, as shown by 

 our drawing (fig. 22) ; but this difference may be due to local 

 variation. The anterior antennfe are five-jointed, stout, and 

 strongly setiferous [iv^. 21). 



The following is Dr. Poppe's definition of the genus : — 

 " Jlujitemannia, nov. gen. — Kiirper vollstandig gegliedert, 

 mit einem s|)itz ausgczogenen Kostrum versehen. Vordere 

 Antcnnen beim $ iiiiifgliederig, bcim (^ zu Greitbrganen 

 umgewandelt. llintere Antennen zweigliederig, mit ein- 

 gliederigem Nebenasl versehen. Erstes Fusspaar zweiiistig,

 gliederigem Aussenast und eingliederigem Innenast. Die
