NOTES ADDED IN PRESS. 



Euphausia pellucida, Dana. Taken in the serial tow-nets of Station 2 of 

 Mr. George Murray's " Oceana" Expedition, 52° 45' N., 12° 27' W., 453 fathoms. 



An oceanic species of very wide distribution, not previouslij recorded from tvitliin 

 the British area. 



Stylocheiron sp. Taken in company with the hist. No member of this genus 

 has hitherto heeti recorded from ivithin the British area. 



Nyctiphanes Couchii (Bell). Evidence presented by a small example (about 

 6 mm. long), taken off Plymouth, points to the absence of exopods on the fifth and 

 sixth pairs of legs in the female of this species, as in N. australis. The imperfect 

 condition of the remaining female specimens in our possession does not permit 

 of the complete establishment of this point. In the female N. norvegica exojiods 

 are present on all the legs (except the last pair, which are quite rudimentary 

 throughout the genus), as in the males of all three species. 



Macropsis Slabber! (Van Beneden). A single specimen taken in a sui-face 

 tow-net at night, Inisbofin Harbour, 5th August, 1899. 



No Previous Irish Record. 



Distribution.— F'lvth of Forth ; Falmouth (A. M. N.*) : Whitsand Bay ; Tamar 

 Estuary. 



Sweden ; Denmark ; Holland ; Belgium ; Mouth of the Seine ; Mediterranean ; 

 Black Sea (A. M. N.*) : Heligoland ; German North Sea Coast (Ehrenbaum) : 

 Channel Islands (Walker and Hornell). 



Erythrops serrata, G. 0. Sars. Specimens from the Clyde, communicated by 

 Mr. W. T. Caiman, agree in particulars of serrulation of the inner uropod with the 

 Irish examples.
