LEODICIDvE OF THE WEST INDIAN REGION. 



63 



Ehlers (1887) described a single specimen collected at 321 fathoms in latitude 

 28° 42" N., longitude 38'' 40" W. While his figure would indicate that his specimen 

 was much contracted, it seems to have been about the size of the one I found at Key 

 West and to agree with it in most respects, though he stated that it is without eyes. 

 He figured the ventral acicula as smooth, while in mine it was bifid. He described a 

 posterior three-pointed lip in the anterior parapodia, which does not appear in his 

 figures, and he probably referred to the two cirri and the post-setal lobe, which together 

 give the three-lobed appearance (text-figure 201). 



Specimens from Trieste, under stones on the southern coast of the Bay of Muggia, 

 were described by v. Marenzeller (1874). In size and in number and arrangement of 

 gills these agree with the Key West specimen. There were some differences in the 

 number of the teeth on the paired plates, but these differences I consider unimportant. 



Audouin and Milne Edwards (1834) figure the anterior region of the body and 

 parapodia, but not the jaws. Their figures and descriptions are not different from the 

 above of the Florida specimen. Quatrefages (1865a) gives no figures, but his diagnosis 

 of the species shows no differences except in the position of the gills and the number 

 of their filaments, which are evidently matters of individual variation. 



Mcintosh (1910) de.scribed and figured the living animal as well as details of jaws and 

 setae. His specimen is figured without eyes, but this detail is not mentioned in the text.
