'The following concerning a primitive species of sand-launce {Embolichthys mitsukurii) from Formosa is quoted 

 from Jordan: — 



" the most primitive species of sand-lance, Embolichthys mitsukurii, occurs in Formosa. In this 



species, alone of the sand-lances the ventral fins aie retained. These are jugular in position, as in the Zoarcidce, 

 and the rays are I, 3. The discovery of this species makes it necessary to separate the Ammodytidm- ■ ■ .widely from 

 the Percesoces." 



Nevertheless not being certain where otherwise to place the family Ammodytidae I leave it provisionally 

 in Percesoces where Boulenger puts it, but it appears evident from the position of the pelvic fins in the above named 

 species that its affinities are elsewhere. 



2 " Chiasmodon may be referred to the Percesoces, as the pelvic fins have only a ligamentous 



connexion with the pectoral arch." Boulenger.
