and lucifera were dredged at Station V., Firth of Forth, in April, the one 
on the 24th and the other on the 26th. Diéastylis tumida, Lilljeborg, 
was obtained in a bottom tow-net gathering from 60 fathoms, about ten 
miles off Aberdeen, collected on August 21st, and Pseudocuma similis, 
G. O. Sars, was dredged at Smith Bank, Moray Firth, on February 
15th, and at Station V., Firth of Forth, on April 24th; this is an 
addition to the crustacean fauna of the Forth. The two species belong- 
ing to the Cumellide, Cumella p ygmea, G. O. Sars, and Nannastacus 
unguiculatus, Bate, were obtained in some bottom mud brought up in a 
tow-net about 22 miles to the north of the Shetland Islands on May 17th. 
Cumella was also observed ina gathering collected in Uyea Sound between 
Unst and Uyea Island on the 18th, and also in some dredged material 
from the west end of Station VI., Firth of Forth, collected on the 22nd 
ay yon | of the same month. In this last gathering the somewhat rare but widely 
GokH ty distributed Pseudecwma pulchella, G. O. Sars, was also obtained.

Sub-Order SCHIZOPODA. 
In the gatherings forwarded by the ‘‘Garland” from the Firth of 
Forth during the past year, the schizopod Hrythrops goesit was, as 
usual, of frequent occurrence. Previous to the investigations instituted 
by the Fishery Board this species had not been recognised as a member 
of the British fauna. Hrythrops elegans, G. O. Sars, has also been 
obtained in the Forth estuary during the past year, and the curious 
copepod-parasite Aspidoecia normani, Giard and Bounier, was found 
adhering to a specimen of both Erythr ops elegans and goesu. Siriella 
armata (M. Edw.) was obtained in the Firth of Forth in a bottom tow- 
net gathering from Station IV. collected on April 22nd, and Striella 
crassipes in a gathering from Station V. collected on April 24th. 
Mysidopsis angusta, G. O. Sars, was obtained in the same gathering with 
Siriella crasstpes, and in a gathering from Smith Bank, Moray Firth. 
Rhoda raschii (M. Sars) was, as usual, frequent in many of the gatherings 
forwarded to the Laboratory. It will be observed that the Rev. Mr. 
Stebbing has restored Mr. Sim’s generic name Ahoda for the group to 
which this species belongs.* 
Sub-Order MACRURA. 
Pasiphea sivado (Risso) was obtained in 95 fathoms in Loch Linnhe 
on April 2nd, 1900, but the tow-net gathering in which it occurred was 
not examined till the following March. A specimen of Pandalus 
montagut (with Phryxus (?) abdominalis attached) was found in a gather- 
ing from Station IIL, Firth of Forth, collected on May 9th. A specimen 
of Spirontocaris securifrons, Norman, which also had a Phryxus (?) 
abdominalis attached to its abdomen, occurred in a bottom tow-net 
gathering collected in 78 fathoms, 110 miles north-east of Buchan-ness, on 
May 15th, while Spirontocaris pusiola, with what appeared to be the 
same species of parasite, was obtained in a gathering collected in the Forth 
to the west of Queensferry on April 26th. Crangon (Cheraphilus) nanus 
was obtained at Station V. on April 26th, and Calocaris macandrece was 
obtained at the same station as well as at Station III.; this Macrurid
