abdominal segment (fig. 6). Length about -67 mm. (about ^\ of an 

 inch). The antennules (fig. 7) are short and composed of seven joints ; 

 the first three joints are moderately large, but the others are small. 



The antennae and mouth organs are not unlike those of Laophonte 

 intermedia, except that the second maxillipeds are long and narrow, and 

 the terminal claw very slender and elongated (fig. 8). 



The first pair of thoracic feet are slender, and the first joint of the inner 

 two-jointed branches is elongated and narrow, but the second joint is 

 short and armed with a moderately stout terminal claw ; the inner 

 branches are three-jointed, and just about half as long as the first joint 

 of the inner branches (fig. 9). 



The second, third, and fourth pairs, which are somewhat similar to each 

 other in structure, are also slender. The fourth pair is represented by the 

 drawing (fig. 10). In this the outer branches are of moderate length, and 

 composed of three sub-equal joints, but the inner branches are short and 

 two- jointed, the first joint being a small one. 



The fifth pair (fig. 11) are comparatively large and foliaceous, and have 

 a general resemblance to those of Laophonte similis; the basal joint, 

 which is sub-triangular in outline, is produced interiorly so that its apex 

 reaches to about the middle of the secondary joint ; there are three stout 

 setae on the inner margin of the basal joint and two smaller apical setae. 

 The secondary branch is sub-ovate, somewhat longer than broad, and pro- 

 vided with about five setae on the lower half of the outer margin and 

 apex, the second seta from the inside is of moderate length, but the 

 others are short. One ovisac with several small ova. 



Habitat. — In an old quarry at Granton into which the tide ebbs and 

 flows. Rare. This is different from any species known to me. 



The following other species of Laophonte were also found in the same 

 gathering with the species just described : — 



Laophonte littorale, T. Scott. 

 Laophonte intermedia, T. Scott. 

 Laophonte hispida (Brady and Robertson). 

 Laophonte thoracica, Boeck. 

 Laophonte inopinata, T. Scott. 

 Laophonte curticauda, Boeck. 



Laophonte lamellifera (Claus). 



1863. Cleta lamellifera. Die frei-lebenden Copepoden, p. 123, 

 t. xv., figs. 21-25. 

 This fine species occurred sparingly in a gathering of copepods washed 

 from some dredgings collected in shallow water off Musselburgh, Firth of 

 Forth. In the same gathering, as well as in another from near the same 

 place, collected by means of a hand-net, between tide marks, another 

 Laophonte, L. intermedia, T. Scott,* was much more frequent, and as it 

 somewhat resembles L. lamellifera might be mistaken for it, but 

 L. intermedia has shorter f ureal joints, and the outer branches and 

 second basal joint of the first pair of thoracic feet have a dense covering 

 of minute hairs, which may frequently be seen without dissection. 



Laophonte denticornis, T. Scott.

One or two specimens of this species were found in the same gathering
