near the extremity with a strong spine, with two weaker spines 

 immediately anterior to it. 



Length 5 inches. 



Hal. Port Jackson. 



6. Penseus granulosus, sp. no v. 



Rostrum rather short, not reaching so far as the end of the 

 antemiary scale, very slightly recurved, with ten small teeth 

 above, situated close together anteriorly — the intervals between 

 consecutive teeth increasing progressively from before backwards, 

 the last separated from the penultimate by a wide interval ; 

 under surface toothless, with a fringe of very long cilia. Rostrum 

 continued backwards into a blunt carina, which is non-sulcate, and 

 reaches to the posterior margin of the carapace ; no lateral sulci. 

 Carapace granular. Supra-orbital spine present, small ; antennary 

 and hepatic spines present ; gastro-hepatic sulcus almost obsolete. 

 Eyes large. Antennules with the flagella sub- equal, nearly equal 

 in length to the peduncle. External maxillipedes hairy, the first 

 three joints of the endopodite broad, compressed ; flagellmn 

 reaching hardly as far as the distal end of the second joint. 

 Ambulatory limbs progressively increasing in length to the third 

 pair ; fourth shorter than, fifth equal to the third pair. First and 

 second pairs both unispinous, third non-spinous. Surface of 

 abdomen minutely granular ; third, fourth, fifth and sixth segments 

 with a mesial dorsal carina, which ends in a small spine on the 

 sixth segment. First, second, fourth and fifth rings with a 

 lateral notch on their posterior border ; those on the first and 

 second segments shallow and open, those on the fourth and fifth 

 rather deeper. Seventh segment mesially grooved; its apex acute, 

 but not developed into a spine ; its lateral margin with a single, 

 weak spine. 



The above is the description of the adult female. From the 

 same localities are a number of small male specimens, which seen 

 to be the males of this species ; they differ from the females in
