Forty-five Lumpsuckers were examined in April. In the stomach of 

 one captured on the 11th a single Amphipod {Amathilla sp., jun.) was 

 observed. In the stomach of one captured on the 13th one Pandalus 

 montagiii, a number of Calanus finmarchicus, and one or two Hyperids 

 (gen. et sp. V), were obtained as well as the remains of Annelides, and a 

 considerable quantity of whitish semi-fluid matter, consisting partly at 

 least of Ccelenterata. In the stomach of a male Lumpsucker captured on 

 the 16th the following organisms were noticed — fragments of several 

 Pandalus monfagui, one young Amatliilla (sp. 1), a few specimens of 

 Temora lonr/icornis, and the remains of several Annelids ; in the stomach 

 of another captured at the same time there was a quantity of matter con- 

 sisting apparently of small Coelenterates. In the stomach of a specimen 

 captured on the 18th I obtained AmathiUa hotnari and the remains of 

 some Annelids, while fragments of Pandalus wontagui were obtained in 

 the stomachs of two collected on the 29th. Small Coelenterates occurred 

 in the stomachs of two of the five Lumpsuckers collected on the 30th of 

 Api'il ; the Coelenterates were numerous in one of the stomachs referred 

 to along with the remains of Annelids, but only a few Coelenterates were 

 observed in the other. 



Thirty-three Lumpsuckers were captured in May. Seven speci- 

 mens were collected on May 1st, but only t-wo of them contained 

 food, which consisted of a considerable quantity of small Coelenterates ; 

 and in the stomach of another collected on the 2nd, fragments of 

 a moderately large Idothea (/) haltira were observed ; Temora longi- 

 cornis, the remains of at least four Annelids, and a few larval 

 Balani (cypris stage) were also obtained. Five Lumpsuckers 

 were captured on May 3rd, and the stomach of one of them was well 

 filled with what looked like small Coelenterates, and mixed up with 

 them were a number of Temora longicornis, apparently only recently 

 swallowed, one or two Calanus finmarchicus, larval Balani (cypris 

 stage), and the remains of one or two Annelids. On the fins of this 

 specimen several small tumours were observed, which, when opened, were 

 found to contain numerous but extremely minute living Psorosphfera^ ; 

 some were of a globular form and filled with granular matter, but the 

 greater plumber were pear-shaped and furnished with two flagella at the 

 narrow end. The gall-bladders of some of these fishes were also infested 

 with larval Cestoids, and similar organisms were of frequent occurrence in 

 the intestines. One Idofhea pelagica and a number of Temora longicoriiis 

 were mixed up amongst a quantity of whitish semi-fluid matter in the 

 stomach of one of four Lumpsuckers collected on the 9th, and numerous 

 specimens of Temora, mixed up with similar whitish matter, occurred in 

 the stomach of another; both of these stomachs were those of male fishes. 

 Ten Lumpsuckers were captured between the 13th and 16th of the month, 

 and the stomachs of three or four of them contained small Coelenterates 

 and remains of Annelids. 'Temora longirornis and larval Balani were 

 also frequent. Seven Lumpsuckers were captured in the month of June 

 and three in July, but after the 18th of the latter month no more were 

 obtained, and they appear to have loft the Bay about that time. The 

 stomachs of two of those obtained in June contained small Cnelenterates 

 and Temora longicornis, and one of those captured in July was also 

 filled with Coelenterates consisting for the most part of Pletiro- 

 brachia. It may be of interest to note the fact that the stomachs 

 containing food which could be most easily identified were usually 

 those of male fishes; the great majority of the stomachs of female 

 fishes examined were either empty or contained a thin fluid differing 

 little, if at all, from sea water. The apparent absence of food in 

 the majority of adult Lumpsuckers has been taken special notice of
