44 CRUSTACEA COPEPODA. II. 
where Pleury. platessa does not live, Mag. sc. Traustedt has taken a typical specimen of C. flure and besides 
3 specimens, which are rather slender and more similar to the typical C. cornutus than to C. flure; all 4 spec- 
imens have probably lived on Drepanopsetta. 
Occurrence. — Taken by the “Ingolf’’ at two places, on Pleuronectes platessa. 
North-West Iceland: Dyrefjord; 10 females. 
East Iceland: Seydisfjord; 6 females. 
At West Greenland it has been found at Jakobshavn and Egedesminde, perhaps also at Godthaab. 
— Mag. sc. W. Lundbeck has, as already mentioned, gathered it in Onundarfjord, North-West Iceland; 
at South-West Iceland it has been found in Havnefjord (Fritz Johansen). — Dr. A. C. Johansen took a 
considerable number on Pleur. platessa at Thorshavn, Stré6m6, one of the Feeroes. 
Distribution. — “Various parts of the British coasts” (T. & A. Scott); Roscoff (C. Vogt); Belgium 
(v. Beneden) ; Bohuslan, in Plewronectes flesus and P. limanda (Olsson); Skager Rak not far from the Danish 
coast (Olsson); Massachusetts (Mary Rathbun).

11863. Chondracanthus Limand@ Kroyer, Nat. Tidsskr. 3. Rekke, B. II, p. 322, 330, Tab. XIV, fig. 2, a—b. 
!IQ13. — limande T. & A. Scott, Brit. Paras. Cop. p. 174, Pl. XLVII, fig. 6; Pl. LVI, figs. rz, 12. 
The three females from our area agree so much with Kroyer’s description and figures of C. Limande 
and differ so sharply from the other species established on parasites on flat fishes, that they must be referred 
to that form. The first thoracic segment is dorsally very short and nearly confluent with the second segment, 
which is broad, moderately long and with a pair of large, dorso-lateral, rounded protuberances; second legs 
are somewhat short, thick, and nearly inflated. 
Occurrence. — Taken by the “Ingolf”’ at a single locality. 
Feroes: Trangisvaag, on the lower branchia and in the gill-cavity of Pleuronectes flesus; 3 females. 
Firth of Clyde, Moray Firth, and Irish Sea; on Pleuronectes limanda (T. & A. 
Scott). — Kattegat, on the same flat fish (Kroyer). 
Distribution. 
55. Chondracanthus clavatus Bassett-Smith. 
1896. Chondracanthus clavatus Bassett-Smith, Ann. Mag. Nat. Hist. 6. ser. Vol. XVIII, p. 13, Pl. V, fig. 6. 
! 1913. — —  T.&A. Scott, Brit. Paras. Cop. p. 175, Pl. XLVI, fig. 7; Pl. LVI, figs. 14, 15. 
Occurrence. — ‘Taken by the “Ingolf”’ at a single locality. 
Feeroes: Trangisvaag, below in the branchial cavities and on the lowest gills of Pleuronectes micro- 
cephalus; 12 females. 
Furthermore 9 specimens have been taken on the same flat fish at the same locality by Mag. sc. 
R. Horring. 
Distribution. — Hitherto only recorded by British authors, from Plymouth, Firths of Forth 
and Clyde.
