Other Observations. 



There are a number of other tow-nettings, taken with 

 either an ordinary surface net or the shear net, from 

 various localities throughout the district. I do not 

 propose to consider these in detail, but shall merely offer 

 a few notes on some of the organisms found in them. 



Muggiaea atlantica occurs in four of our catches. 

 It was first observed on September 12th, on which day it 

 occurred in the following localities: — 4 miles N.E. of 

 Carnarvon Bay Lightship; 5 miles S. of Carnarvon Bay 

 Lightship; 3 miles N. of Causeway Buoy, Cardigan Bay. 

 All these hauls were made with the shear net, about 

 10 fathoms deep. It was most abundant in Cardigan 

 Bay, but was also in fair quantity in Carnarvon Bay. 

 Another catch made on this date, further south in 

 Cardigan Bay, was unfortunately lost by breakage of the 

 bottle in transit from Fleetwood to Liverpool. The other 

 gathering in which Muggiaea occurs is a shear-net haul 

 made near Causeway Buoy on October 8th. It did not 

 occur in any other Cardigan Bay catches on this date, 

 and there are no catches from Carnarvon Bay for this 

 month. This is the first time Muggiaea has been 

 observed so far north in our waters. 



Autolytus prolifer occurred sparsely in various 

 localities during most of the period. In the second half 

 of January swarms of pelagic males and females were 

 encountered in three localities : — Near Carnarvon Bay 

 Lightship; off Maughold Head, Isle of Man; and about 

 half-way between Morecambe Bay and the Calf of Man. 

 In Cardigan Bay, at the same period, only a few 

 individuals, all males, were taken. In most of the 

 females the ova were in a pretty advanced condition, and 

 in some they had evidently recently hatched out, a few 

 embryos, of three or four segments, being still in the
