pelagic boreal amphipod, Euthemisto, which was taken frequently 

 from this point on, while a swarm of Sagitta elegans gave a new aspect 

 to the tow. Clione, too, was represented by several large specimens. 

 There were neither Aurelia nor Cyanea so far off shore; but the four- 

 foot net yielded several large Beroe cucumis, a cosmopolitan form 

 already often recorded from the Gulf. Perhaps associated with the 

 abundance of Calanus, were the numerous Wilson's petrels which 

 surrounded the ship as soon as we hove her to at this station. From 

 Station 7 we ran in shore again, and worked for two days in Ipswich 

 Bay, a region where I had previously found an abundant plankton, 

 and which is proverbial for whales, sharks, etc., and the seat of an im- 

 portant winter fishery. Calanus finmarchicus was still the prevalent 

 organism, the nets bringing back a swarm of juveniles, besides several 

 Euchaeta norvegica, great numbers of Sagitta elegans (Stations 8, 9, 

 10, 11, 12b), Tomopteris helgolandica, represented by a very large 

 specimen in the quantitative haul at Station 11, and, among Medusae, 

 Aurelia and Cyanea in large numbers, with a few Melicertum campan- 

 ula, and Phialidium languidum. The latter species we found very 

 widely distributed in the coastal waters of the Gulf. 



But the most important feature of Ipswich Bay, to us, was the 

 immense number of pelagic fish eggs, largely Urophycis chus: and a 

 haul of the eight-foot beam trawl for thirty minutes at Station 8 

 yielded the following large haul of fishes; twelve skates (Raja radiata) 

 two Aspidophoroides monopterygias, four Zoarces anguillaris; twenty 

 silver hake (Merluccius bilinearis,) two hake (Urophycis regius), 

 thirty -four squirrel hake, (Urophycis chus), two rocklings (En- 

 chclyopsis cimbrius), forty-one sanddabs (Hippoglossoides plates- 

 soides), six rusty flounders, (Limanda ferrugnea), forty-eight witch 

 flounders (Glyptocephalus cynoglossus), and seven large goosefish (Lo- 

 phius piscatorius) . The squirrel hake (Urophycis chus) were full of 

 ripe eggs and milt; and comparison of their eggs, fertilized on board, 

 with the pelagic eggs taken in the tow, established the identity of the 

 most abundant of the latter as belonging to this species. This dis- 

 covery is of great interest, because very little is known of the early 

 stages of any members of this genus, and nothing of this particular 

 species. It, and the other fishes will be described by Mr. W. W. Welsh. 

 Meantime it may be noted here that the fish were spawning in twenty- 

 two fathoms, temperature 42.4°, salinity 32.39%o. In spite of the great 

 numbers of pelagic eggs, Ipswich Bay and the waters immediately to 

 the north yield#l but few fry, except for the sanddab (Hippoglos- 

 soides), of which twenty-four specimens of 10-22 mm. were taken at
