(fig. 150) of usual caligoid type with about six 

 teeth. First maxilla (fig. 150) with inner poste- 

 riorly directed process near mouthtube and outer

Remarks. — This species is closely related to L. 

 tylosrin {= rornufii.<<) also commonly found on 

 needlefishes. A discussion of the characters used to 

 separate these two species and of the host speci- 

 ficity of each follows the description of L. tylosurl.
