BERTELSEN AND MARSHALL: MIRAPINNATOIDEI 



383 



cover at least the main "V" of each element, and such an ar- 

 rangement seems to be unusual in teleosts. Similar wide red 

 muscle coverage of the myotomes is found also in the stomia- 

 toids and giganturoids (Marshall, unpublished) and apparently 

 alsoinmaleceratioidangler-fishes(Marshall, 1971).Othergroups 

 will probably prove to have this kind of red muscle arrangement 

 but the most usual condition in teleosts is a narrow concentra- 

 tion of red muscle on either side of the horizontal septum down 

 the entire length of the fish. However, in alepisauroids the ver- 

 tical extent of red muscle expands towards the tail, where it may 

 cover most of the myotomes (Marshall, 1971; Johnson, 1982). 

 The above treatment of adult characters indicates that the 

 mirapinnatoids are most closely related to the megalomycter- 

 oids. Next to the latter they are most nearly allied to the ceto- 



mimoids. As will be seen from the title of this paper, we have 

 followed Greenwood et al. (1966) in placing all three suborders 

 in the order Cetomimiformes away from the Acanthopterygii. 

 Whether they can be gathered into a larger ordinal grouping, as 

 in the Lampridiformes (Rosen and Patterson, 1969) or in the 

 Beryciformes (Rosen, 1 973), is a matter for further comparative 

 studies (see also Zehren, 1979). Nothing is known of larval 

 megalomycteroids and cetomimoids. Larval forms of other 

 groups seem to have no affinities to larval mirapinnatoids.

Beryciformes: Development and Relationships 

 M. J. Keene and K. a. Tighe 



IN the classification of Greenwood el al. (1966), the order 

 Beryciformes was divided into 3 suborders; the Stephan- 

 oberycoidei with 3 families, the Polymixoidei with I family and 

 the Berycoidei with 8 families. Rosen and Patterson (1969) re- 

 moved the Polymixiidae from the Beryciformes, assigned it to 

 a new order, the Polymixiiformes and placed this order in the 



Paracanthopterygii. Rosen and Patterson (1969) also moved the 

 Cetomimidae, Barbourisiidae and Rondeletiidae to the Bery- 

 ciformes in the suborder Cetomimoidei. Woods and Sonoda 

 (1973) considered the order Berycomorphi to contain the fam- 

 ilies Polymixiidae, Diretmidae, Monocentridae, Anomalopidae, 

 Trachichthyidae, Holocentridae, Berycidae, Sorosichthyidae, and
