Ampeliscaspi7iipes,Boeck=zA.tenicicor?iis,^eip. III., 207. 



Throughout the L.M.B.C. district in 20 to 50 fath. 

 Length 17 mm. This is the commonest species in the dis- 

 trict, the preceding one being the next commonest. I have 

 little doubt that the species figured as A. gaimardii (Kr.) in 

 the British Sess.-eyed Crust, is this species and not as Sars 

 supposes, A. typica (Bate). I have examined Bate's speci- 

 men, in the British Museum, and find both it and the figure 

 to confirm this view. The relative proportions of the upper 

 and lower antennae which are correctly drawn, are alone 

 sufficient to show that it cannot be A. typica. 



Ampelisca macrocephala, Lilljeborg. 



Port Erin, Aug., 1893 (W. A. H.). Length 10 mm. 

 Resembles A . brevicomis in the form of the hind margin 

 of the third pleon segment, but may be distinguished most 

 readily by the greater length of the upper antennae, and 

 by a long spine near the tip of the outer ramus of the 

 second uropods. 



Haploops tubicola, Lillje. 



One specimen between Isle of Man and Orme's Head, 

 20 to 30 f., 28/8/86. Length 8 mm. 



Amphilochuxe. 



Amphilochus manudens, Bate. 



Little Orme, Aug. and Sept., '89; Gt. Orme, 8 f., 

 1/4/90 ; Puffin Island ; Menai Bridge, 5 to 12 f ., April and 

 May, '94; 2 m. S.E. of Kitterland, Isle of Man, 17 f., 

 27/5/94. Colour generally brownish, sometimes almost 

 black ; one specimen from Gt. Orme bright scarlet. Eyes 

 red, rather small. Length 2 J mm. 



Amphilochus melanops, n.sp.* (PI. XVIII. , fig. 12; PI. 

 XIX., figs. 13—15).
