it may be but casual visits, at least to this part of the kingdom. 

 I have never yet missed H. ohlivia a single season since I began 

 to look to these things, and was able to go out. The same may 

 almost be said of L. Kinahani and S. galha. But although I 

 have not met with these so invariably, nor even with H. medusarum 

 and minuta, still that is no proof that they are not as regular, or 

 nearly so, in their visits as H. ohlivia, though fewer in numbers. 

 It is hardly possible, in fact it is impossible, that one individual 

 could see all that happened every year, even in this small way 

 and though but in a single district ; still I think I am not far from 

 the mark. It will be as well, however, in the meantime, perhaps, 

 to look upon H. medusarum and S. minuta, but especically the 

 latter, as but casual or accidental visitors only. And it is, I 

 believe, during these peregrinations that on coming too near the 

 land so many of them, as in the case of S. oblivia, are occasionally 

 washed in and destroyed. 



Lestrigonus KinaJiani and Hyperia galha generally appear here 

 about the beginning of July, and disappear again towards the end 

 of Sej)tember ; JBL. ohlivia usually about August, and continues 

 till spring; S. medusarum in December, and remains till March 

 (on one occasion I took two of this species as late as the month of 

 May) ; and the time I found II . minuta was from October to 

 December. During these periods, too, I have never failed to find 

 the females of all, save the first, to contain, in some cases eggs, 

 in others well-developed young. "With reference to H. ohlivia, I 

 not unfrequently find females of this species with young from 

 September to January, thus extending over a period of five 

 months. 



Although I have taken H. ohlivia from the stomachs of dif- 

 ferent species of fish besides the herring, I have never yet found 

 any of the other in a heterogeneous repository of the kind. 



There is yet another circumstance which I would here mention, 

 as being, in some measure, in connexion with my subject. Of 

 itself, however, it may be of little or no value, but when taken in 

 conjunction with the others will, I trust, be at least found worthy 

 of record. It is that, during some seasons when the Medusce were 

 very plentiful, I have noticed that the 'Hyperics (I here allude 

 only to L. Kinahani and H. galha) would be remarkably few, and 

 vice versa. And during no season, within my recollection, has 

 this been so much and so strikingly the case as in the present 

 (1866), the Medusod having been far more numerous here than 

 ever they were known before. Now, and from this circumstance,
