Localities. Off Fernandina, Florida; off Georgia; off St. Augustine, 

 Florida; latitude 31 57' north, longitude 78 18' 35" west. 



Depth,. 263-tl40 fathoms. 



Body oblong-ovate, about two and a half times longer than wide, 

 7 mm. : 18 mm. 



Head about twice as wide as long, rounded anteriorly and produced 

 in the middle in a small, narrow process, separating the basal articles 

 of the antenna and meeting the small frontal lamina on the other side. 

 The eyes are large, oblong, and conspicuous, occupying almost the 

 entire surface of the head and contiguous in the median line. The 

 first two articles of the first pair of antennae are small and equal in 

 length; the third article is long and narrow, nearly three times as long 

 as the second article. The flagellum is composed of sixteen articles. 



The above description is adapted from the following one of Schioedte and 

 Meinert' s: 



Ovata, supra prseter puncturam ordinariam punctis mlnutis, perraris sparsa. 



Frons bisinuata, acumine procumbente dimidiam partem articuli primi anten- 

 narum primi paris discernente. 



Lamina frontalis rhomboidalis, Oculi magni, oblongi, post acuminati, seriebus 

 ternis ocellorum contigui. 



Antennae primi paris angulum posticum annuli primi trunci vix attingentes, scapo 

 articulum quartum, flagello articulum decimym antennarum secundi paris explentes; 

 flagellum 7-8 articulatum, articulo primo perlongo, tenui, articulos tres sequentes 

 conjunctos longitudine sequante. 



Antennae secundi paris dimidiam partem epimeri quinti explentes; flagellum 21 

 articulatum. Segmentum dorsale annuli primi trunci ante late emarginatum; seg- 

 mentum dorsale annuli septimi maximam partem obtectum. 



Epimera latiuscula; anguli postici epimerorum posteriorum acuti, paulum pro- 

 ducti; epimerum ultimum annulum primum caudalem explens. Pedes prensorii 

 graciles, subglabri; femora angustiuscula; ungulse primae pusillae, posteriores ali- 

 quanto majores magisque incurvae. 



Pedes gressorii longiusculi, robustiores, parce spinulosi. Annulus primus cau- 

 dalis maximam partem obtectus. Annulus analis producte lingulatus, supra sub- 

 aequatus, ad basin obscure bifoveolatus, margine terminali profunde crenulato, medio 

 in dentes septem exeunte. Pedes anales longiusculi; ramus interior quam exterior 

 multo longior et duplo latior, post in obliquum late rotundatus; ramus uterque post 

 in dentes plures obtusiusculos desinens.
