antero-lateral regions, presents some longer yellowish hairs among 
the dense down with which 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 which 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. hybrida. It differs, however, first, by the armature 
of the upper surface of the cephalothorax, the dentiform tubercles 
of D. hybrida 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. hybrida, 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 Hyastenus Pleione, Herbst.) 
Four specimens (2 ¢,2 2) of this new species are in the Col- 
lection, of which two ( ¢ @ ) were collected at Elphinstone Island 
and two (do 2) at King Island Bay. 
This new HHyastenus 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 Pletone and communicated to me 
the characters by which this new species differs from that of 
Herbst. I therefore have much pleasure in dedicating this 
Hyastenus to the learned carcinologist of Berlin. As regards its 
outer appearance, our new species much resembles H. Pleione, 
Herbst, and H. diacantha, de Haan; it may, however, easily be 
* J was unable to compare the description of Lepidonaxia Defilippii 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.ML.S. ‘Alert,’ 1884, 
p. 195).
