CARL BOVALLIUS, AMPHIPOUA HYPERIIDEA. 1. 2. 



The tenth family ANCHYLOMEBIDiE, C. BOVALLIUS, 1887. 



Diagll. Caput magnum, tumidum, plus minusve globosum. Oculi grandes. Antenna! primi paris recta?, 

 parti anteriori capitis affixrc; articulus primus flagelli crassus elougatus, ceteri in mare plus 

 minusve numerosi, filiformes, in f'emina nulli. Antenna; secundi paris in mare longas fili- 

 formes, parti anteriori capitis affixre, in f'emina obsolete. Instruments oris masticatoria, 

 mandibular in mare palpo instructs, in femina palpo carentes. Pedes perazi parium quattuor 

 mediorum prensorii, vel pedes quinti paris solum prensorii; pedes septimi paris plus mi- 

 nusve transformati vel reducti. Pedes uri ramis distinctis carentes. 



Tbe head is large, tumid, more or less globose. The eyes are large. The first pair of 

 antennae are straight, fixed on the front side of the head; the first joint of the flagellum is 

 thick and elongated; the following are more or less numerous in the male and filiform, in 

 the female they are wanting. The second pair of antenna? in the male are long and fili- 

 form, fixed on the front side of the head; in the female they are obsolete. The mouth- 

 organs are adapted for mastication; the mandibles in the male are furnished with a palp, 

 in the female without a palp. The four middle pairs of perceopoda, or only the fifth pair, 

 are prehensile; the seventh pair are more or less transformed or reduced. The uropoda 

 want distinct rami.

The genera composing the family Anchylomeridie were previously united under 

 the name Phrosinince as a subfamily of the family Phronimidce (see above p. 330, 331 

 and 341). 



In 1887 I proposed the new family-name Anchylomeridar, considering the Phro- 

 sinince so different from the Phronimidce, that they ought to form an independent family. 



In 1888 Stubbing changed the name to Phrosinidce, but as Anchyloineridee has 

 priority by a year and is taken from a generic name still in use within the family I 

 must reject the later name. Another practical reason why Anchylomeridaa ought to be 

 retained instead of Phrosinince is that the latter name sounds very like Phronimidce and 

 would possibly make confusion. 



The first described genus belonging to the family was Phrosina instituted in 1822 

 by Risso; in 1829 Latreille applied the name Dactylocera to the same genus. 



In 1830 H. Milne-Edwards founded the new genus Anchylomera; which in 1832 

 was called Cheiropristis by Cocco; and in 1836 Hieraconyx by Guerin Meneville.
