Psalidopodidae fam. nov. „Olfactory flagellum of antennules simple. 

 Mandible deeply divided into molar and incisive processes, and furnished with a 

 2-jointed palp. The exopodite of the first maxillipede is a broad and abruptly 

 incurved falsiform plate which does not terminate in a flagellum, and is not 

 expended at the outer margin into a process. The exopodites of the 2. and 3. 

 maxillip. are undivided, poorcit and membranous flagella. The thoracic appen- 

 dages from the 2. to the 8. incl. have the 3. and 4. joints fused, 6-jointed, with 

 the exception of the 3. pair, in which the 6. and 7. joints are in addition fused, 

 and there are hence only 5 distinct joints; those of the 4. pairs are formed as 

 in the Crangonidae, but, instead of terminating in a subchela, end in two 

 equal and movable blades forming a scissors-like organ; those of the 5. pair, 

 which are the shortest and weakest of the limbs, bear a probably expansible 

 pencil of setae at the distal end of the propodite; the dactylopodite is reduced 

 to a minute nidiment; the 6., 7., and 8. pairs form a backwardly increasing 

 series of Walking legs; the 5 last pairs are devoid of all traces of epipodites 

 and exopodites. 



In addition to the functional gills, 5 pleurobranchiae attached to the 

 posterior thoracic somites from the 10. to the 14. incl., there is present, on the 

 arthrodial membranes of the thoracic appendages from the 9. to the 13. incl, 

 a series of 5 small conical papillae, which correspoud to the arthrobranchiae of 

 the Glyphocrangonidae. — The body is exceedingly spiny and terminates in front 

 in a powerful recurved rostrum, which is tothed on all its 4 margins."

Chirostylidae nov. Fam. Galatheid; A Ortmann, S,244: Kiemen phyllo- 

 branchiat, wahrscheinlich 14 (10 Arthrobranchien, 4 Pleurobr.). Aeufsere Antennen 

 4-gliedrig, das verschmolzene 2. u. 3. Glied lang, an der Spitze mit einem festen 

 Dom (Rest der Scaphoceriten?). Geifsel reduzirt. Innere Antennen an der 

 Basis mit stachligem Styloceriten. Abdomen beim rj auf p und q mit Sexual- 

 anhängen, r, s, t ohne Anhänge. Rostrum fehlend und daher das Augensegment 

 frei liegend wie bei den Paguridea, aber ohne Schuppe an der Basis der Augen- 

 stiele. Cephalothorax Pagurus-ähnlich, nach hinten weich, ohne scharfe Seiten- 

 kante und ohne deutliche linea anomurica. Die Familie ist begründet auf die 

 neue Gattung Chirostylus, S. 246, mit den Merkmalen der Familie. Stylo- 

 cerit der inneren Antennen bandförmig, in mehrere Domen verlaufend. — Ch.
