242 Messrs. T. and A. Scott on some 



Hah. Also among Filograna, from the Moray Firth. 

 Several specimens were obtained. 



Remarks. This species somewhat resembles Pseudanthessius 

 Thorellii (B. & R.), but differs particularly in the form of 

 the anterior foot-jaws, in the proportional length of the inner 

 branches of the fourth thoracic feet, and in the form of the 

 abdomen. 



Eemigulus *, gen. nov. (provisional name). 



Body cyclopoid. Anterior antennge short, six-jointed. 

 Posterior antenna three-jointed, without a secondary appen- 

 dage. Mouth-organs rudimentary — the mandibles, maxillae, 

 and foot-jaws consist for the most part of simple stylet-shaped 

 appendages. The first four pairs of thoracic feet have all the 

 outer branches three- and the inner two-jointed. Fifth pair 

 unbranched, two-jointed. 



The genus Eemigulus is provisionally instituted to include 

 a curious cyclopoid copepod from Loch Linnhe, west of Scot- 

 land. The following is a description of the species : — 



Remigulus tridens, sp. n. 

 (PL XI. figs. 15-20; PI. XII. figs. 1-3.) 



Basal joints of the six-jointed anterior antennas armed with 

 threeprominent teeth (PI. XII. fig. 1); when the animal is viewed 

 from above the basal joints with tlieir armature are entirely 

 hidden by the boldly rounded forehead. The formula shows 

 the proportional length of the joints of the anterior antennae — 



7 . 10 . 12 . 4 . 5 . 6 

 12 3 4 5 6* 



Posterior antennae stout, the second and third joints subequal 

 and shorter than the first ; the second joint is more or less 

 covered with cilia and armed with a stout hooked spine at 

 the distal end ; the last joint, which is narrower than the 

 preceding one, bears four spiniform and geniculate terminal 

 setae. Mandibles and other mouth-organs as described in the 

 generic definition (PL XI. figs. 17, 18, 19; PLXlLfig.2). The 

 first and second joints of the outer branches of the first pair of 

 swimming-feet are furnished exteriorly with a marginal row 

 of small teeth ; the joints of the short and stout inner branches 

 are subequal and are each provided with a plumose seta on 

 the interior edge, while the second joint is strongly dentate 

 on the outer margin and armed at the apex with two small 

 hook-like spines. The inner branches of the next three pairs
