this volume). Cololabis is the only scomberesocid with fila- 

 ments, a polar cluster of relatively long filaments plus a single 

 long lateral filament (Fig. 173B). Cololabis eggs typically are 

 attached to floating objects such as kelp. 



Belonid eggs have filaments (Table 90). typically long, nu- 

 merous and uniformly spaced over the chorion (Fig. 1 74A). In 

 at least one species, Strongylura strongylura. some filaments are 

 markedly longer than others (Fig. 1 74B), as in the adrianich- 

 Ihyids. The filaments on eggs of Tylosaurus acus are arranged 

 in uniformly distributed tufts containing 2-3 filaments each (Fig. 

 174C). 



Hemiramphids have eggs with attaching filaments (Rhyn- 

 chorhamphus. Hyporhamphus, and Hemiramphus. Fig. 175A), 

 pelagic eggs with very short uniformly-spaced filaments (O.xy- 

 porhamphus. Fig. 175B), or are viviparous (Hemirhampliodon, 

 Dermogenys, Nomorhamphus). Filaments were not reported on 

 ovarian eggs of Dermogenys by Flegler (1977) and we did not 

 note their presence in Hcmirhamphodon or Zenarchopterus but 

 this needs to be checked more thoroughly. Kovalevskaya (1965) 

 reported that filaments on Rhynchorhamphus georgii have a 

 bipolar arrangement; however, this is not clear in her illustration 

 (Fig. 175 A). Talwar (1968) and Sudarsan (1968b) reported the
