MR. E. J. MIERS ON THE 



§§ Anterior legs ivith ilie fingers excavated at the tijps. 



ScHizoPHRTS, White (Bione, De Haan, nom. prseoc). Cara- 

 pace orbiculate-triangular or rarely elongated. Spines of rostrum 

 distinct, T^-ith one or more accessory spines upon their outer mar- 

 gins. Orbits large. Basal joint of antennae rather slender, with 

 two spines at its distal end. Type Schizophrys aspera (Milne- 

 Edwards) . 



The fingers are acute and not excavated in S. dama (Herbst), 

 a species which differs from others of the genus in its more elon- 

 gated form, and approaches the MaiidaB. 



Cyclax, Dana. Carapace orbiculate or oblong-orbiculate. 

 Spines of rostrum simple, very short or rudimentary. Orbits 

 large. Basal joint of antennae usually much enlarged. 



The accessory spines of the rostrum of Schizophrys constitute 

 the only positive distinction (although an arbitrary one) that can 

 be employed to separate the species of that genus from Cyclax 

 and Nemausa. 



Subgenus 1. Cyclax, Dana. Spines of rostrum longer. Eye- 

 pcduucles longer. Basal joint of antennae slenderer, with two 

 spines at its distal end. Type Cyclax 'Perry Dana. 



Subgenus 2. Cyclomaia, Stimpson. Spines of rostrum rudi- 

 mentary. Eyes large. Basal joint of antennae very broad, with 

 three spines at it^ distal end. Type Cyclomaia suhorhicularis, 

 Stimpson. 



(The genus ^'Fletu^ophrictcs of Alphonse Milne-Edwards, founded 

 upon a species, P. cristatipes, from Australia (Journ. Mus. Godef- 

 froy, iv. p. 84, pi. xii. fig. 6, 1873), is placed by that distinguished 

 carcinologist among the Oxyostomata ; but judging from the de- 

 scription and figure of the third maxillipede, I should certainly 

 suppose its true position to be in this subfamily of the Oxyrhyncha. 

 It is distinguished from Cyclax, Schizophrys, and Temnonotus by 

 tbe anterior legs, whicb are short and somewhat enlarged, and 

 by the front, which is quadridentate.) 



Subfamily 3. Micippin^. (See Plate XIII. figs. 1, 2, 3.) 



Carapace suboblong. Rostrum vertically, or nearly vertically, deflexed, 

 usually broad, lamellate. Anterior legs with the fingers acute at tips. 

 Basal antennal joint very much enlarged. Eye-peduncles very long, geni- 

 culated, and laterally projecting.
