. Contributions to a monograph of the Amphipoda Hyperiidea. Hyperiidea. KONGL. SV. VET. AKADEMIENS HANDLINGAR. BAND. 22. N:0 7. 197 9. HYPERIA FERA, J. D. DANA, Hyperia fera, Dana.

Caput magnum, segmentis quinque primis peraei paullo brevius. Segmenta omnia pei'cei libera. Pedes percei primi paris pedibus secundi paris breviores. Pedes tertii ac quarti parium pedibus secundi paris plus quam duplo longiores. Pedes parium trium ultimorum duobus prrecedentibus paullo longiores; dactylus dimidium metacarpi longitudine rcquans; carpus pedum quinti paris tibia non longior. Latera segmentorum plei post rotundata. Pedun- culus pedum uri ultimi paris plus quam duplo longior quam latior. Telson segmento ul- timo uri brevius, ac dimidio pedunculi pedum uri ultimi paris multo brevius. The head is large, and only a little shorter than the first five perasonal segments together. All the pergonal segments are free. The first pair of perazopoda are shorter than the second pair. The third and fourth pairs are more than twice as long as the second pair. The last three pairs are somewhat longer than the two preceding pairs; the dactylus is half as long as the metacarpus; the carpus of the fifth pair is not longer than the tibia. The lateral parts of the pleonal segments are rounded behind. The peduncle of the last pair of uropoda is more than twice as long as broad. The telson is shorter than the last ural segment, and much shorter than half the peduncle of the last pair of uropoda. Colour. "Brownish, or brownish red in irregular spots, partly colourless; basal joints of six posterior legs, brownish red.» (Dana.) Length. About 3 mm. »One-eighth inch.» (Dana.) Hab. The tropical region of the Atlantic: »Lat. 2° N. to 1° S., Long. 18° to 17° W.» (Dana.) Syil. 1852. Lestrigonus ferns, J. I).
