HYALINOECIA TUBICOLA. 315 



From H. tuhicola (Miiller), apparently so common farther south, this species 

 is distinguished in having the branchiae begin farther forward and in their 

 clearly greater length; in having the peristomium much larger in comparison 

 with somite II; in the different proportions of the tentacles; and in the details 

 of structure of setae and jaws. In the small H. juvenalis Moore the branchiae 

 may similarly begin on somite XIX; but, among other differences, that form 

 has conspicuous eyes, whereas the present one has none, and differs in the form 

 and size of postsetal and presetal lips of the parapodia, in the fewer teeth of 

 maxillae III, in the much smaller peristomium, which is only one third as long 

 as somite II, and in the presence of compound setae on the first parapodia.
