EUROPEA.K FORMS OP THE CIROLANINiE. 349 



' Porcupine' (1869) St. 36 : lat. 48° 50' K, loag. 11° 9' W., 725 

 fatlioms (the locality at the entrance of the English Channel), 

 one specimen in Canon Norman's Collection. 



Remarks. — Of this small and blind deep-sea species only a 

 preliminary description, without figures, has been published. 

 [In the original manuscript I gave only an abstract of this 

 description; but having subsequently received a specimen from 

 Canon Norman, some additional observations have been inserted. 

 G. cceca is sharply distinguished from C Schinidtii and G. neglecta 

 by the absence of eyets and of farrows on the epimera ; it is much 

 more related to the preceding species than to C. Qnicrophthalmci,, 

 Hoek, and allied exotic forms.]

 "Eyes very small, black." 



Erontal plate " narrow, elongate and canaliculated." 

 Antennulse about as long as the peduncle of the antennae, 

 rather similar to those of G. horealis. 



Antennae with the flagellum very much shorter than in 

 G. horealis, G. gallica,ox G. neglecta, consisting of at most thirteen 

 joints. 



(Epimera of seventh thoracic segment probably considerably 

 larger in proportion to those of sixth segment than in C. gallica 

 or G. neglecta.') 



Seventh thoracic legs have the second joint less flattened and 

 about three and a half times longer than broad, with a few short 

 setae near the base of the outer margin, no setae on the inner 

 margin except on its distal end, and a rather small number of 

 setae along the ridge on the lower surface. Fourth joiat elongate, 

 a little longer than the fifth and much longer than the sixth. 



Last abdominal segment posteriorly either rounded or " ob- 

 tusely truncated," with about three pairs of short spines. 



Uropoda moderately broad. Endopod, when directed parallel 

 with the axis of the animal, reaches a little beyond the end of 

 abdomen ; it is nearly two and a half times as long as broad, its 

 outer margin considerably bent — convex or nearly angular — 

 beyond the middle, but the distal part more or less distinctly
