318 CARL BOVALLIUS, AMPHiroDA IIVPERIIDEA. 1. 2. HYPEKIID^E. 



Genus 9. PHRONIMOPSIS, c. CLAUS, 1879. 



Diagn. Caput magnum, altius quam longius. Perceon leve, epimera cum segmentis coalita. Pedes 

 percei priiiii paris simplices, non subcheliformes; carpus angustus. Pedes secundi paris 

 dactylo-cheliformes^); carpus minimus, valde productus; processus carpi styliformis; meta- 

 carpus maximus, valde productus; processus metacarpi robustus, tuberculatus, ante anguste 

 excavatus. Carpus pedum tertii ac quarti parium non dilatatus. Pedes parium trium 

 ultimorum cheliformes, longitudine subiBquales, pra2cedentibus multo longiores; metacai'pus 

 non elorigatus. Pedes uri elongati. 



The head is large, and deeper than long. The perason is smooth; the epimerals are coalesced 

 with the corresponding segments. The first pair of perwopoda are simple, not subcheli- 

 form; the carpus is narrow. The second pair are dactylo-cheliform; the carpus is very 

 short and rauch produced; the carpal process is styliform; the metacarpus is very large, and 

 much produced; the metacarpal process is robust, tuberculated, with the front side very 

 narrowly excavated. The carpus of the third and foiu'th pairs is not dilated. The last 

 three pairs are cheliform, subequal in length, and much longer than the two preceding 

 pairs; the metacarpus is not elongated. The uropoda are elongated.

The genus Phroniinopsis is remarkable chiefly by the peculiar prehensile organ of 

 the second pair of perteopoda, formed by the strongly produced metacarpus and the dac- 

 ti/lus, and not as usually by the carpus and the metacarpus. 



Claus in 1879 placed the genus in the family Phronimidce, and gave the follow- 

 ing diagnosis: 



»Körper zoea-ähnlich, mit gedrungenem, fast kugligem Vorderleib, schmalem, langgestrecktem 

 Adomen und 3 Paar langer stilförmiger Uropoden. Kopf kurz und hoch. Die beiden vordern Brust- 



^) This peculiar form of prehensile organ, wMch I propose to eall a »daotylo-cheliform hand» will 

 be closely described below under Phronimopsis Sarsi (p. 322).
