FLYING FISH IN MEDWAY AND SWALE. 409 



Fig 2. 



Fig. 2. — Sonie of the ovarian eggs, in different stages of development, 

 with their adherent intervening mucous membrane, from the Swale Flying 

 Fish (Exocostus lineatus), as sketched under the microscope. While con- 

 firming Haeckel's observations on the fibrillar nature of the egg-envelope of 

 Exoccetus, the specimen moreover shows tbe filaments' tendency to stream 

 out. Compare fig. 4 below, and consult Ryder's descriptions and illustrations 

 as quoted.

Fig. 3. — Unripe egg of the Saury Pike or Skipper (Scombresox saurus), 

 showing the net-like envelope of fibres or filaments surrounding it, among 

 which are seen a few of their swollen bases of attachment (after Haeckel). 



Fig. 4. — Ripe eggs of the Gar-Fish (Belone vulgaris), with their wavy 

 free filaments intertwined (after Mcintosh and Masterman).
