The Amphipoda of Bermuda. 23 



In male, first gnathopods strongly atrophied, rudimentary ; epimeron 

 triangular; second joint rather broader distally than proximally ; 

 third joint rather longer than usual ; fourth, fifth, and sixth joints 

 scarcely distinguishable, last joint forming very weak claw. 



Second gnathopods with strongl}^ developed hand ; epimeron more 

 or less oval, not large ; second joint very slender at base but broaden- 

 ing regularl}- to distal end where anterior margin is produced to 

 form a rather large rounded lobe ; third joint small ; fourth much 

 narrower than third with a distal triangular process ; wrist triangular, 

 cuplike, not as long as broad, with short posterior margin provided 

 with a number of setae ; hand suboval, about twice as long as 

 broad, anterior margin convex, posterior margin about half as long 

 as anterior, palm oblique and very irregular, bearing 3 deep rounded 

 indentations and numerous setae of different lengths, anterior sub- 

 margin and apex with several fascicles of setae ; finger rather stout 

 and curved, of usual form. 



Pereiopods rather long and slender and subequal with epimera 

 which are longer than high ; second joint long and slender ; third 

 joint small ; succeeding joints elongated and subequal ; claws small. 

 Pereiopods of posterior group with second joints slender in proximal 

 half, strongly dilated in distal half; succeeding joints very similar 

 to those of anterior pereiopods. 



Uropods, 3 pairs, biramous, all extending to about same distance 

 posteriorly ; rami broad, styliform, slightly serrated on margins ; rami 

 in all uropods subequal. 



Telson entire, suboval, rather longer than broad with apical margin 

 very slightly indented. 



The species was represented by a single male specimen 4 mm. 

 long. It has been reported from the Mediterranean and the British 

 and French coasts. 



Panoploeopsis gen. nov. 



Posterior margins of posterior thoracic and anterior abdominal 

 segments produced to form median dorsal teeth. Rostrum acute ; 

 epimera 1—3 more or less acutel}^ tapering, fourth with posterior 

 margin produced to form pointed process. 



Mandibles narrowl}' tapering to cutting edge, accessory plate 

 narrow, no spine row, molar tubercle rudimentary, palp 3-jointed. 

 Lower lip rather elongate, without inner plate and with anterior 

 margins of outer plates entire. First maxillae with inner plate bearing 

 setae on inner margin and apex, outer plate rather long and nar-
