Length of the palm 7^/2 mm. 



Height of the palm near the articulation with the 



fingers 7 » 



In adult specimens the cephalothorax has a breadth of 

 1^/4 inch and is then twice as large as our individual. 



Heteropanope serratifrons Kinahan inhabits the eastern 

 coast of Australia and New Zealand.

 Pilumnus glohosus, Dana, 1. c. p. 236, PI. XIII, fig. 10. 



Two specimens (cf and Q) of which the locality is unknown. 



The cephalothorax of this species is rather thick , and , 

 being but little broader than long, greatly resembles the 

 species of the genus Actumnus. The upper surface is very 

 convex in the antero-posterior direction ; the regions are 

 very faintly indicated and the sutures defining the gastric 

 region are scarcely visible. The upper surface is covered 

 with a few scattered , small granules and densely with 

 rather short yellowish hairs. The front is very narrow , the 

 distance between the internal angles of the orbits measures 

 scarcely a third of the greatest width of the cephalothorax. 

 It is much deflexed , prominent and divided in two lobes 

 by a narrow but deep incision. The finely granulated and 

 straight margins of these two frontal lobes run obliquely 

 backward and are not separated by an incision from the 

 upper orbital margins , quite as in the genus Sphaerozius 

 Stimps. The external orbital angle is formed by a small 

 rather acute granule, the inferior orbital margin presents 

 some similar granules and the internal angle of the latter 

 terminates in a somewhat larger granule. The basal joint 

 of the outer antennae is very short and even the second 

 joint does not yet reach the frontal margin ; the length 

 of the flagellum is still a little shorter than the breadth 

 of the front. The antero-lateral margins are a little longer 

 than the postero-lateral ones ; they are entire , and orna-
