126 AUSTRALIAN MALACOSTRACA. 



Carapace rhomboidal, in general outline similar to that of P. 

 lambriformis. Front emarginate ; antero- lateral borders with 

 three conical teeth, the first rather larger than the others, a fourth 

 smaller tooth at the junction of the antero-lateral and postero- 

 lateral borders ; postero-lateral border with three compressed 

 conical teeth ; three prominent, sub-equal, conical teeth behind, 

 the mesial tooth situated above the other two, the latter situated 

 immediately above the insertion of the abdomen. Upper surface 

 closely granulated, a broad smooth longitudinal ridge on the 

 gastric region, followed by a row of three conical tubercles ; on 

 either side of the posterior portion of the mesial ridge, an ovoid 

 tubercular eminence, with the long' axis longitudinal ; branchial 

 region with a few small tubercles. Arm, carpus, and propodos 

 closely granulated, the granules on the first coarser than those 

 on the two last ; dactyli finely toothed, incurved at their points. 

 Abdomen (female) covered with flat granules, a small tooth in 

 the middle of the distal border of the composite segment. 



Port Molle (Whitsunday Passage), 14 fath. (W.A.H., H.M.S. 

 "Alert.") 



A second, smaller, male specimen from the same locality, 

 differs from this mainly in having the upper surface of the 

 carapace free Brom granulations.

Phlyxia granulosa, Haswell, 1. c, p. 54, pi. vi., fig. 3. 



Carapace rhomboidal, closely granulated, the posterior border 

 armed with two triangular compressed teeth ; cardiac region 

 elevated to form a prominent pyramidal eminence surrounded by 

 a narrow fissure, continuous with which anteriorly is a pair of 

 similar fissures separating the genital region from the branchials. 

 G-enital region armed with a short, blunt spine ; a pair of similar 

 spines on the posterior half of the gastric region, and one on each 

 branchial region; on each hepatic region a triangular tooth, 

 bounded behind by a narrow fissure similar to that which surrounds 

 the intestinal eminence. Front moderately prominent, bidentate. 

 Sternum and external maxillipedes covered with close-set granules, 

 which become elongated into spinules towards the anterior 

 extremities of the latter. Limbs covered all over with similar
