Dermatomyzon nigripes (Brady and Robertson). 
1875. Cyclopicera nigripes, Brady and Robertson, Brit. Assoc. 
Report p. 197. : 
This fine species occurred in only one of the gatherings at present 
under consideration—viz., in a bottom tow-net gathering from Station 
XY. (Moray Firth), collected 20th November 1897. 
Rhynchomyzon purpurocinctum (T. Scott). 
1893. Cyclopicera purpurocinctum, T. Scott, Eleventh Ann. Rep. 
Fish, Board for Scot., Part IIL, p. 209, Pl. IIIL., figs. 29-40. 
This well-marked species was obtained in the gathering from Station 
XV. (Moray Firth), in which Dermatomyzon nigripes occurred, and in 
another collected at Station II., also in the Moray Firth, 5th November 
1897. In this species the last three thoracic segments are of a dark 
purple colour. Dr. W. Giesbrecht has found Rhynchomyzon pur- 
purocinctum in Naples Bay. 
Neopontius angularis (T. Scott). 
1898. Neopontius angularis, T. Scott, Sixteenth Ann. Rep. Fish. 
Board for Scot., Part IIL, p. 271, Pl. XIV., figs. 1-11. 
This species was described in 1898 from specimens obtained at Otter 
Spit, Upper Loch Fyne. I have now to record it from a bottom tow-net 
gathering from Station IV. (Kilbrennan Sound), Firth of Clyde, 
collected 24th August 1898 (27-29 fathoms).

Hist., ser. 6, vol. xvi. p. 183 (August 1895). 
This species, described in 1888 in the Sixth Annual Report of the 
Fishery Board for Scotland, has recently been re-examined, and some 
further details of structure have been elucidated which I now propose to 
notice by way of supplementing the original description. 
The length of the specimen figured is 1‘2mm. (,}, of an inch). The 
first thoracic segment is equal to rather more than half the length of the 
thorax and abdomen combined; the abdomen is moderately elongate, and 
the furcee are rather longer than broad. In general appearance this species 
somewhat resembles Cribropontius normani (B. and R.) (fig. 7, Pl. XII). 
The antennules are eight-jointed. The first and second joints are elon- 
gate; the third to the seventh are comparatively short; while the last is 
about twice the length of the penultimate joint (fig. 8, Pl. XII.). The 
proportional lengths of all the joints are approximately as shown by the 
formula—

A moderately long asthetask springs from the end joint, as shown in 
the figure. 
The antenne are apparently four-jointed, and a very small secondary 
branch bearing two minute hairs springs from the end of the second joint
