antero-lateral regions, presents some longer yellowisli hairs among 

 the dense down witli whicli it is covered. 



I do not venture to describe these specimens as a new species, 

 as they are apparently very young. 



As regards Doclea muricata, Fabr., of whicli I was enabled 

 to examine the typical specimen preserved in the Museum of 

 the University of Kiel, I will observe that this species is closely 

 allied to D. Jiyhrida, It differs, however, first, by the armature 

 of the upper surface of the cephalothorax, the dentiform tubercles 

 of D. hyhrida being substituted in D. muricata by acute and longer 

 spines ; and, secondly, by the fourth antero-lateral spine being 

 nearly twice as long as the third. The chelipedes of the male 

 are, moreover, comparatively smaller. As regards the shape of 

 the cephalothorax and the form and the length of the ambulatory 

 legs, Doclea muricata much resembles D. hyirida, the legs of the 

 second pair being even in the male a little shorter than twice the 

 length of the cephalothorax.

(Compared by Dr. Hilgendorf, of the Zoological Museum of 

 Berlin, with the typical specimens of Syastenus Pleione, Herbst.) 



Tour specimens (2 d* , 2 $ ) of this new species are in the Col- 

 lection, of which two ( c? $ ) were collected at Elphinstone Island 

 and two ( c? $ ) at King Island Bay. 



This new Syastenus is closely allied to Hyastenus Pleione, 

 Herbst. Dr. Hilgendorf, kindly compared for me one of the four 

 specimens, a male, which I had sent him, with the (four) typical 

 specimens of Herbst's Cancer Pleione and communicated to me 

 the characters by which this new species differs from that of 

 Herbst. I therefore have miich pleasure in dedicating this 

 Syastenus to the learned carcinologist of Berlin. As regards its 

 outer appearance, our new species much resembles S. Pleione, 

 Herbst, and S. diacantha, de Haau ; it may, however, easily be 



* I was unable to compare the description of Lepidonaxia Befilippii of 

 Targioni-Tozzetti, a species described in 1877 in the 'Zoologia della Magenta'; 

 according to Mr. Miers, however, this species may probably be regarded as a 

 mere variety of H, oryx, A. M.-Edw. (Zoology of H.M.S. 'Alert,' 1884, 

 p. 195).
