Diagii. Caput magnuni, tumiduin, plus minusve globosuui. Oeuli grandes. Antennce primi paris rectaj, 

 parti anteriori capitis affixaa; articulus primus flagelli erassus elongatus, ceteri in mare plus 

 minusve numerosi, filiformes, in femina uuUi. Antenna; secundi paris in mare longre fili- 

 formes, parti anteriori capitis affixte, in femina obsoletfe. Instrumenta oris masticatoi"ia, 

 mandibula3 in mare palpo instructaa, in femina palpo carentes. Pedes percei pariuni quattuor 

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

 nusve transformati vel reducti. Pedes uri ramis distinctis carentes. 



The liead is large, tumid, more or less globose. The et/es are large. The tirst pair of 

 antennas 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 antennas 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 peraiopoda, or only the fifth pair, 

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

 waut distinct rami.

The genera composing the family Anchylomerida3 were previously united under 

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

 and 341). 



In 1887 I proposed the new family-name Anchylomerida3, considering the Phvo- 

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



In 1888 Stebbing changed the name to Phrosinidce, but as Anchylomeridas has 

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

 must reject the låter name. Another practical reason why Anchylomeridffi 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 Clieiropristis by Cocco; and in 1836 Hieraconyx by Guérin Mbneville.
