BIGELOW: EXPLORATIONS IN THE GULF OF MAINE. 101 



Station 11. In Kittery Harbor, however, we obtained great numbers 

 of Tautogolabrus and Merluccius. 



Our enforced return to Gloucester for repairs on July 18 gave us 

 an opportunity to compare the plankton off the Harbor mouth (Sta- 

 tion 12) with what we had found a week or two previous, with the 

 result that there had been no appreciable change, the waters still 

 being filled with the Calanus swarm besides an occasional Euchaeta, 

 and a few fish eggs, and many fry, as noted above. 



Our run from Cape Ann to Casco Bay showed that the spawning 

 area of the squirrel-hake, admitting our identification of the pelagic 

 eggs to be correct, extended over the whole coast band, large hauls of 

 fish eggs, including this species, being made at Stations 14 and 20. 

 At the latter many cunner eggs (Tautogolabrus) were also taken; 

 and a few eggs probably belonging to the mackerel, which were school- 

 ing in small numbers in this neighborhood at the time. Mackerel eggs 

 were likewise taken in our surface tows at our anchorage at Orr's 

 Island, on August 1 . Only two species of fish fry were taken in num- 

 bers in the northwest corner of the Gulf and in Casco Bay. Most 

 important of these, because of its purely boreal habitat, is the redfish 

 (Sebastes marinus), no less than 320 larvae of which were taken in the 

 closing net and in the intermediate haul at Station 19 (p. 108). At 

 Station 22, likewise, it was represented by fifty-three specimens, in 

 the open net haul. In Casco Bay, larval cunners (Tautogolabrus) 

 were numerous. 



Along this stretch of coast we continued to find Calanus finmarchicus 

 in large numbers, with a few Euchaeta norvegica; and at Station 13 

 we captured a few of the large blue copepod Anomalocera patersoni on 

 the surface, a species frequently taken after this, occasionally in large 

 numbers (p. 118); and several other copepods in lesser numbers, as 

 shown in the table (p. 115). Off Cape Porpoise we first encountered 

 the amphipod Euthemisto in large numbers. Here, too, our tows 

 revealed many specimens of the pteropod Limacina balea; while 

 Stations 19 and 22 added a fresh Chaetognath, Sagitta serratodentata 

 in small numbers. Another addition to the plankton, in this region, 

 was the large hydromedusa Staurophora mertensii, which we first met 

 at Station 14, where three large specimens were taken in a haul of the 

 four foot net from twenty fathoms. Meganyctiphanes norvegica, too, 

 occasionally occurred in our hauls off Casco Bay, (Station 19). In 

 the coast region Aurelia and Cyanea were taken in most of the hauls, 

 but usually not on the surface; though several large specimens were 

 seen floating at Station 22. Our most notable find in this region was
