IO CRUSTACEA COPEPODA. II. 
Remarks. — The differences pointed out between my single specimen and Giesbrecht’s figure and 
description of S. longifurca are so conspicuous that it is deemed necessary to establish the new species. 
Occurrence. — Taken by the “Ingolf’”’ at a single deep station. 
South-West of Iceland: Stat. 78: Lat. 60°37’ N., Long. 27°52’ W., 799 fathoms, temp. 4°5; I specimen. 
Acontiophorus Brady. 
Of this fine genus not only the two species known from Great Britain and Norway have been found 
in our area, but it has even been necessary to establish a third species from very deep water.

An exceedingly large female, measuring 2.26 mm. to the end of the caudal rami, agrees in most features 
well with the descriptions and figures published by Sars and Giesbrecht. The antennule (fig. 6 a) contain 
exactly the same number of joints as stated by these authors, and the relative length of the joints is char- 
acteristic; besides antennee, maxille and maxillipeds agree completely with the figures quoted. The only 
differences observed are the following. The two anterior thoracic segments have the posterior margin rather 
concave, as the lateral parts of each segment is produced somewhat backwards and the posterior corner is 
a rather acute angle; third segment has the broad median part of the posterior margin very concave, while 
the lateral part of the segment is not produced backwards but directed outwards, and each postero-lateral 
corner is distinctly rounded. — Fifth pair of legs agrees excellently with Brady’s drawing (I. c. fig. 15), as 
the rather broad end has 2 setee, the outer (anterior) margin has a single seta and the inner (posterior) margin 
2 setee, while in Giesbrecht’s and Sars’ figures of this leg the rather produced end is much more narrow with 
a single seta, and the inner margin has 3 sete. 
Occurrence. — Taken by the “Ingolf” at a single deep-sea station. 
Davis Strait: Stat. 24: Lat. 63°06’ N., Long. 56°00’ W., 1199 fathoms, temp. 2°4; I female. 
Distribution. — Ris6ér, southern coast of Norway (G. O. Sars); east coast of England near Scar- 
borough (Brady); finally in the Mediterranean at Naples (Giesbrecht) and at Triest (Claus).
