Genus 9. PHRONIMOPSIS, C. GLAUS, 1879. 



Diagn. Caput magnum, altius quam longius. Perceou leve. epimera cum segmeDtis coalita. Pedes 

 perai primi paris simplices, non subcheliformes; carpus angustus. Pedes secundi paris 

 dactylo-cheliformes 1 ); carpus minimus, valde productus; processus carpi styliformis; meta- 

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

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

 ultimorum cheliformes, longitudine subasquales, prancedentibus multo lougiores; metacarpus 

 non elongatus. Pedes uri elong-ati. 



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

 with the corresponding segments. The first pair of pera>opoda are simple, not subcheli- 

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

 short and much 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 fourth 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 Phronimopsis is remarkable chiefly by the peculiar prehensile organ of 

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

 tylics, and not as usually by the carpus and the metacarpus. 



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

 ing diagnosis: 



»Korper zoea-ahnlich, mit gedrungenem, fast kugligem Vorderleib, schmalem, langgestrecktem 

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



J ) This peculiar form of prehensile organ, which 1 propose to call a "dactylo-cheliform hand" will 

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