The species was found in abundance at both the above 

 localities, living among Zo.stera and other weeds inside the coral 

 reef at depths ranging from low water to two fathoms. The speci- 

 mens were obtained in an environment closely similar to that in 

 which H. varians abounds on the English and Irish coasts and, at 

 the time of capture, it was thought they must certainly belong 

 to that species. 



In colour the majority were of a brilliant green ; but very 

 many other types, each having its counterpart in home waters, 

 were observed. The collection, which was made in February, 191 3, 

 contains a high proportion of ovigerous females.

Specimens of this species received in exchange from the 

 Australian Museum differ from those of the preceding form in 

 possessing no teeth on the dorsal margin of the rostrum and in 

 having from four to six teeth (rarely three) ventrally. The 

 ultimate segments of the antennular peduncle are shorter and 

 broader, the second being broader than long, the antenna! scale 

 (in an ovigerous female) is three and a third times as long as 

 broad and the last segment of the third maxillipede is scarcely twice 

 the length of the penultimate. The proportions of the segments 

 in the carpus of the second peraeopods are also different (fig. 6). 

 The middle segment, as in H. varians and H. ventricosus , is 

 much the shortest, but the third is decidedly longer than the 

 first. The last three pairs of legs are stout. In an ovigerous 

 female the propodus of the fifth pair is only five and a half 

 times as long as broad and is little more than twice the length 

 of the dactylus (spines included).
