520 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [8] 



A fragment of the posterior Nectocalyx. 



Family DIPHYID^. 



Epibulia aurantiaca, Voo-t. 



DlPHYES, Sp. 



MtJGGIiEA, sp. ? 



Among the Diphyid-like Medusae are mauy specimens which have 

 the anterior nectocalyx only. All of these I have placed in the genus 

 Muggicea, following Chun * in his limitation of the generic name Muggiac 

 to Diphyids with one nectocalyx, which resembles the anterior necto- 

 calyx of the genus Diphyes. Our Atlantic species somewhat resembles 

 M. kochii, but differs from it in several particulars. In the absence of 

 more knowledge of the live animal, I will provisionally refer this to an 

 unknown species of Muggicea.
