Habitat. — Vicinity of Inchkeith Island and other parts of the Forth. 

 Not uncommon. The second last pair of pereiopods are comparatively 

 long. The epimeral plates of the last segment of the metasom have the 

 lower distal angle rounded, and provided posteriorly with a single small 

 tooth on either side, or with two or three small teeth of unequal size.

Habitat. — Vicinity of the Bass Rock (1892), and in other parts of the 

 Forth area. Though not recorded till now, this species has been in my 

 possession for a considerable time. The Forth specimens are comparatively 

 small. Another species of the Ampeliscidse, Byblis gaimardii, Kroyer, 

 has been, on the authority of Metzger,* recorded from the vicinity of St 

 Abb's Head, at the mouth of the Firth of Forth (see Leslie and Herdman's 

 1 Invertebrate Fauna of the Firth of Forth,' p. 105 (Appendix), and 

 ' Revised List of Crustacea of the Firth of Forth,' by the author) ; but G. 

 O. Sars, in his new work on ' The Crustacea of Norway,' does not include 

 the British Islands in his notes on the distribution of the species. It is, 

 perhaps, therefore right to state that I am able to corroborate Metzger's 

 record from having been fortunate in capturing a fine specimen of Byblis 

 gaimardii, Kroyer, near the May Island, in January 1890. Had there 

 been time a description with drawiugs of the species would have been 

 prepared for the present Report, but this may be done later.

1894. Amphilochoides pusillus, T. and A. Scott (31), p. 147. 



Habitat. — Vicinity of the Bass Rock. Not common. This species has 

 no tooth at the base of the dactylus of the first pair of gnathopods, and 

 the palm of the second pair of gnathopods is finely serrate only on the 

 distal half ; the other half is even, or nearly so, and bears a few minute 

 setae. 



Family Stenothoid^e. 



Genus Metopa, Boeck (1870). 



Metopa propinqua, G. 0. Sars. 



1892. Metopa propinqua, G. O. Sars (29), p. 264, pi. xciii. fig. 1. 



Habitat— Off Crail, 1892. Rare. 



The telson of this species is furnished with three strong denticles on 

 each side of the upper surface and near to the margin. The second gnath- 

 opods are also moderately stout. The Forth specimen agrees with Sars' 

 description of the species in all its principal characters. Several of the 

 species of Metcpa are very small and troublesome to diagnose.
