shortly be published. The species to which the zoea 

 belongs is probably P. veterum. In the later parts of 

 the year several kinds of " Megalopa " stages were 

 collected. The greater number of these were the young 

 of Portunus or Hyas, but several are still unidentified, 

 and at present there is no clue to their parents. 



The zoeas and young stages of Anomurans are very 

 common indeed. Galathea larvae were present all 

 through the spawning months, but the species to which 

 they belong is not certain. There is possibly a 

 difference in the species of Galathea larvae which occur 

 at different times of the year, as has been noted below in 

 the case of Ewpagurus. The genus is exceedingly 

 abundant in many stages. 



A curious regularity in the distribution of 

 Ewpagurus was seen in the material examined, but I am 

 not yet prepared to state that this condition of affairs is 

 the rule. During the spring E. bernhardus was 

 exceedingly common in every stage, and in all but one 

 haul E. prideauxii* was unrepresented ; during the 

 autumn E. prideawtii was in its turn as common 

 as its companion species had previously been, and 

 E. bernhardus was now absent in all but one haul. The 

 nettings taken from the " James Fletcher " in Cardigan 

 Bay in the autumn of last year do not, however, support 

 these results, as, although E. prideauxii is exceedingly 

 common, E. bernhardus is almost equally so. 



The lengthy spawning period of E. bernhardus, 

 already referred to in another publication^ is borne out 

 by the occurrence of a 1st zoea stage in Morecambe Bay 

 as early as February of this year. " Glaucothoe " 



* I hope shortly to publish a description of the zoea stages of 

 E. prideauxii.
