CESTODES FROM FLORIDA SHARKS—-CHANDLER 31 
Genus NYBELINIA Poche 
NYBELINIA PALLIATA (Linton, 1924) 
This worm, designated Yetrarhynchus palliatus by Linton, was 
recorded by him from Sphyrna zygaena (Linnaeus) at Woods Hole. 
My specimen comes from the same host. 
NOTES ON TETRARHYNCHIDEAN LARVAE 
I wish to take this opportunity to reallocate, generically, certain 
tetrarhynchidean larvae described by me (1935a), on the basis of 
the classification of this group as worked out by Pintner, Dollfus, 
et al. The species that I referred to as Gymnorhynchus gigas and 
G. malleus should be known as Pterobothrium filicolle (Linton, 1889) 
and P. malleum (Linton, 1924), respectively, since Southwell (1930) 
was evidently in error in considering P. filicolle synonymous with 
Gymnorhynchus gigas (Cuvier, 1817). The species I described as 
Tentacularia lepida, following Southwell’s outmoded system, should 
be transferred to the genus Callotetrarhynchus Pinter, 1931, and be 
known as Callotetrarhynchus lepidus.
