new and rare Crustacea from Scotland. 57 



bluntly rounded and furnished with one moderately long and 

 a few minute setas ; the basal joint is also fringed with small 

 setaj round the outer margin and end ; secondary joint sub- 

 cylindrical and provided with five spiniform and coarsely 

 plumose terminal setse (fig. 20). Caudal stylets very short. 



Habitat. Vicinity of Granton and of Dunbar, Firth of 

 Forth ; rare. 



Remarks. This species is considerably larger than either of 

 the other two Pseudowestwoodias^ 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 

 fifth pair of swimming-feet ; the inner branches of the first 

 pair are also observed to be distinctly more elongate, even 

 without dissection. All the three species closely resemble 

 Westwoodia nohilis (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 

 pools 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, except 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 antennae are five-jointed, stout, and 

 strongly setiferous (fig. 21). 



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

 " Iluntemanma, nov. gen. — Korper vollstandig gegliedert, 

 mit einem spitz ausgezogenen Rostrum versehen. Vordere 

 Antennen beim ? fiinfgliederig, beim ^ zu Greiforganen 

 umgewandelt. Hintere Antennen zweigliederig, mit ein- 

 gliederigem Nebenast versehen. Erstes Fusspaar zweiastig, 

 von den nachfolgenden Fusspaaren abweichend mit zwei- 

 gliederigem Aussenast und eingliederigem Innenast. Die 

 drei folgenden Fusspaare mit rudimentarem Innen- und 

 zweigliederigem Aussenaste. Das iii. Fusspaar beim ^ von 

 dem des $ abweichend. Mandibularpalpus einastig. Un-
