CLASSIFICATION OF THE MAIOID CEUSTACEA, G59 



EuETNOME, Leacli. Carapace subtriangiilar, tuberculated, aud 

 spinose. Spines of rostrum laminate at base, acute at ends, 

 slightly divergent. ISTo prasocular spine. Basal autennal joint 

 enlarged at base, longitudinally suleated, without a spiue at its 

 distal end. Anterior legs in male elongated, much longer than 

 the ambulatory legs, which are all of moderate length. Type 

 Eurynome aspera (Pennant). 



This genus has been placed by Milne-Edwards and other 

 authors in the Parthenopidse ; but in all structural characters 

 it is ob\iously allied to Pisa and Syastenus. 



Pelta, Bell. Carapace subpyriform. Rostrum with the spines 

 united at base, afterwards divergent. 'So praeocular spine. Basal 

 antennal joint elongated ; its distal half visible from above at the 

 side of the rostrum. Legs all of moderate length. Type Felia 

 pulchella, Bell. 



Subfamily 2. Schizophrysin^. 



Carapace very broadly triangular, or oval, or nearly circular. Rostrum 

 very short or obsolete. Anterior legs in male small, slender ; the fingers 

 usually excavated at the tips. 



This subfamily establishes the transition of the Maiidae to the 

 subfamily Mithracinse in the PericeridsB, and includes those 

 Maioids in which the rostrum is reduced, until in Gyclax its spines 

 are represented only by two small tubercles, the orbits often 

 nearly complete, or marked with very narrow fissures, the ca- 

 rapace broadly triangular or nearly circular, the epistome short, 

 the basal antennal joint very largely developed, and the anterior 

 legs with the fingers more or less excavated. 



§ Anterior legs ivitli the fingers acute at tlie tips. 



*Temnonotus, a. Milne- Edwards. Carapace ovate-elliptical, 

 convex and tuberculated above, with a horseshoe-shaped pit on 

 the dorsal surface. A prajocular spine present. Spines of ros- 

 trum simple, well developed. Orbital fissures narrow ; eyes short, 

 thick. Basal joint of antenna? much enlarged. Type Temnonotns 

 granulosus, A. M.-Edwards. 



Only females of this genus are known ; and it is possible that 

 in adult males the fingers may be excavated as in other genera of 

 the same group.
