602 REPORT—1904. 
The telson is somewhat acutely pointed, with the lip semitubular, owing to its 
being arched dorso-yentrally. Length, 9 mm. 
Metamunna typica differs from Plewrogonium in the presence of eyes and eye- 
stalks, and from Paramunna in the absence of the two lobes tothe cephalon. The 
sides of the metasome are serrated as in Paramunna bilobata. Length, 2 mm. 
Ischnosoma Greenit differs from the rest of the species of the genus in the 
absence of large spines from the body, and, in the uniform armature of very small 
spinules. Uropoda one-jointed, as in I. spinosum, I. Thomsoni, and I. quadri- 
spinosum. The superior antenna is very characteristic, having the form seen in 
I. spinosum. 
Ilyarachna Plunketti is closely allied to I. longicornis, but differs in having the 
outer, instead of the inner, corner of the basal joint of the antennule produced. 
From I. hirticeps it differs in the absence of armature from the cephalon. 
Length, 4 mm. 
. Munnopsoides Beddardi, for which a new genus hasbeen erected, differs from the 
typical Munnopsis in having no palp to the mandible and in having the fifth 
segment of the mesosome considerably longer and narrower than the rest. The type 
of the genus is M. australis (Beddard), described from the Challenger expedition. 
This species differs from M. australis in the larger and more massive cephalon, in 
the shape of the maxillipeds, and in the shorter and broader fifth segment to the 
mesosome. Length, 5 mm. 
Lipomera lamellata has been made the type of a new family, the Lipo- 
merida, distinguished by having the seventh segment of the mesosome with its 
appendages very considerably reduced, and in the uropoda consisting of a broad 
lamellar plate folded on itself. 
The family is very closely related to the Munnopside, and especially to the 
genus Lurycope, but the seventh legs, instead of being well developed, with a 
broad lamellar terminal joint beset with long and strong plumose sets, are very 
small and poorly developed, devoid of set, and imperfectly jointed. Length, 
1,25 mm. 
9. Some New and Rare Schizopoda from the Atlantic Slope on the West 
of Ireland.! By KH. W. L. Horr and W. M. Tarrersatt, B.Sc. 
10. Some New Copepoda from the Atlantic Slopes. By G. P. Farran. 
During the dredging cruise to the Porcupine Bank made by the s,s. Helga in 
1901 a number of new species of Copepods were obtained, which are of particular 
interest in that the nearest allies of most of them appear to be Northern forms, 
many of which have been recently described by Professor G. O. Sars in his ‘ Crus- 
tacea of Norway.’ 
A full account of the Copepods taken on this occasion, together with descrip- 
tions and figures of the new species, is in the press, and in the Report of the Fish- 
eries Branch of the Department of Agriculture and Technical Instruction for 
Ireland, but in the meantime a short account of the new forms may be of interest. 
Bradyetes inermis.—This form, for which a. new genus appears to be required, is 
closely allied to Bradgidius and Bryaxis, agreeing with them in the jointing of the 
limbs and in the possession of densely setose antenne. It further agrees with 
Bryaxis in having the lateral edge of the carapace deeply emarginate. 
It differs from both in the absence of spines on the last thoracic segment, and 
in its much slenderer and less strongly chitinosed form. The rostrum is absent. 
Length, 2°57 mm. 
Bryaxis minor.—This species, except for one strongly marked feature, the 
second antenne, agrees minutely with Bryaxis brevicornt (G. O. Sars). Its length, 
however, is only 16mm. Jn this species the terminal joint of the second antenne 
‘ Will be published in the Reports of the Department of Agriculture, Ireland, 
1904.
