18. Taramhlyops rostrata Holt & Tattersall. 
P. rostrata, Holt & Tattersall (1905 and 1906). 
This Speeles is new to the Mediterranean fauna. The depths 
at which it was captured ranged from 950—1100 metres (520 — 
600 fathoms). Thongh but recently described this species has already 
been shown to bave a very extensive horizontal distribntion, having 
been recorded from several points on the Atlantic slope off the west 
coast of Ireland and from the north side of the Bay of Biscay 
(Tattersall 1908). 
19. JPseiidomma calloplura* Holt & Tattersall. 
P. calloplura, Holt & Tattersall (1905 and 1906). 
P. affine, Lo Bianco (1903; nec G. 0. Sars, 1870). 
Holt & Tattersall bave already indicated (1906) the presence 
of this species in the Mediterranean and pointed out that the species 
recorded by Dr. Lo Bianco as P. affine is in reality P. calloplura. 
The present material indicates a distinct tendency in Mediter- 
ranean specimens of this species to a normal number of 4 instead 
of 3 pairs of piumose spines at the apex of the the telson. Of the 
14 specimens in the collection, 5 bave 4 pairs of piumose spines, 
in 4 the apex is asymetrical with 4 piumose spines on one side 
and 3 on the other, 3 bave 3 pairs (the normal number in Irish 
examples), while in the remaining 2 the apex of the telson is broken. 
20. Pseudomma Irruppi sp. n. 
PI. 7 Fig. 7—12. 
Carapace evenly rounded in front with the antero-lateral raar- 
gins rounded but slightly produced. 
Pleon longer than the carapace, the first 5 segments sub-equal, 
the 6. Segment more than one and a half times as long as the 
preceding one. 
Ocular plates(Fig. 7) contiguous; cleft rather sballo w; each piate 
quadrangular in outline ; margins smooth, without teeth or serrations. 
Antennular peduncle (Fig. 8) short and stout; 1. joint concealed 
by the ocular plates, almost Square in shape; 2. joint very short; 
3. joint about equal to the first and hearing on its ventral anterior 
face a rather large blunt process, which has not yet developed the 
antennular brush of setae, characteristic of mature males. 
Antennal peduncle (Fig. 9) very little shorter than the anten- 
nularbut much more slender; the 3 joints subequal in length.
