THE VOYAGE OF H.M.S. CHALLENGER. 
The following species are referable to this subgenus : — 
Lambrus hoplonotus, Adams and White, and vars. longioculis, Miers ; planifrons , 
Miers, and granulosus, Miers. Indo-Pacific Seas (Ceylon to New Caledonia ; 
to 28 fathoms). 
Lambrus pisoides, Adams and White. Philippines. 
Lambrus diacanthus, De Haan. Japan. 
Lambrus sculpius, A. Milne' Edwards. New Caledonia; Fiji Islands (Coll. Brit. 
Mus.). 
Lambrus whitei, A. Milne Edwards ( = Lambrus carenatus, White, nec Milne 
Edwards). Borneo ; China Sea. 
Lambrus curvispinus, Miers. • Java Sea. (This species is perhaps a variety of 
Lambrus hoplonotus). 
Lambrus ( Aulacolambrus ) hoplonotus, Adams and White.

Off Cape York, 8 fathoms, in lat. 10° 30' 0" S., long. 142° 18' 0" E.; Station 186 (an 
adult male). 
This specimen differs from the typical example in having the tubercles of the post- 
frontal and hepatic regions of the carapace even larger and more flattened ; in the middle 
line of the carapace, on the gastric and cardiac regions, are two somewhat more elevated 
and subspiniform tubercles. The six spines of the outer (or posterior) margin of the 
chelipedes are very much elongated and of equal length, and are slightly knobbed at the 
tips. These characters are perhaps sufficient to permit of the distinction of this specimen 
as a fourth variety of this protean species, but for the present I will not designate it by a 
distinct appellation. Its dimensions are as follows : —
