AUSTEALIAN MALACOSTEACA. 229 



415. Neobule algicola. 



Xcobide algicola, Haswcll, 1. c, p. 255, pi. viii., fig. 4. 



Eyes round. Superior antennae as long as the cephalon and 

 first two segments of the pereion ; first segment of the peduncle 

 longer and stouter than the others ; third scarcely distinguishable 

 from the articuli of the flagellum ; flagellum rather longer than 

 peduncle. Inferior antennae equal in length to the superior 

 pair ; peduncle and flagellum subequal. Anterior gnathopoda 

 with the carpus sub-triangular; the propodos longer than the 

 carpus, oblong ; the palm transverse, concave. Posterior 

 gnathopoda with the propodos similar in shape to that of the 

 anterior pair, but larger. Third pair of pereiopoda shorter than 

 the fourth and fifth ; fifth pair longer than the fourth, its basos 

 broader than that of the preceding pairs. Rami of posterior 

 pleopoda extremely short. Telson small, entire. 



Kiama, Illawarra. 



Sub- Family Cyproidides. 



Coxae of gnathopoda very small. Coxae of the first and second 

 pairs of pereiopoda very large. Coxae of the third and fourth 

 pereiopoda small. 



Genus Ctpeoidia, Haswell. 



Body broad. Pereion and pleon of equal length. Coxae of 

 gnathopoda very small. Coxae of the first and second pairs of 

 pereiopoda enormously developed ; and cemented together to 

 form broad and deep lateral shields, concealing almost entirely 

 the gnathopoda and pereiopoda, and extending forwards to the 

 sides of the cephalon, and backwards as far as the posterior 

 border of the sixth segment of the pereion, excavated posteriorly 

 for the shallow coxae of the third pereiopoda. Coxae of the last 

 two pairs of pereipoda very small.* Antennae subequal, superior 

 without an appendage. Mandibles with a palp. Maxillipedes 

 unguiculate ; both basos and ischium armed with small squami- 

 form plates. Gmathopoda subcheliform. Pereipoda slender. 

 Posterior pleopoda biramous. Telson single. 



* The coxae of the third and fourth pereiopoda are not amalgamated, as 

 erroneously stated in the original description, but that of the fourth pair is 

 entirely rudimentary and covered by that of the third.
