168 A. Alcock— Carcinological Fauna of India. [No. 2, 
Sub-family IN ACHING (see Table I.). 
Alliance I. Leptopodioida (see Table I.). 
Lambrach^us, n. gen. 
Closely allied to Leptopodia and Metoporaphis , from which it differs 
(1) in its extremely long sub-cylindrical neck, (2) in its minute antennae 
and (3) in the Lambrus-like proportions of its chelipeds. 
Eyes antennules and antennae borne at the end of a long narrow 
subcylindrical “neck,” which is continued onwards as an extremely 
long slender spiny rostrum. 
Eyes stoutish, salient and non-retracticle: no defined orbits: a 
small postocular spine. Antennae minute, exposed to dorsal view. 
Chelipeds stout and extremely long, with long sub-cylindrical palms 
and short fingers. 
Legs very slender: shorter than the chelipeds. 
Lambracliseus ramifer , n. sp., Plate III. fig. 1. 
The body is formed by (1) a small trunk, (2) a long narrow almost 
cylindrical prestomial “neck,” and (3) a long slender sinuous spiny 
rostrum shaped like a withered branch. 
The carapace proper is trilobed, the lateral lobes being formed by 
the branchial regions, and the front lobe being formed by the wings of 
the buccal frame. 
The “ neck,” at the end of which are borne the eyes, antennules, 
and antennae, is rather longer than the carapace proper. 
The rostrum is nearly twice the combined length of the neck and 
carapace. 
The eyes are salient and non-retractile, and though there is a 
narrow dorsal eave round the base of the eyestalks and a pair of tiny 
postocular spines, there is nothing like an orbit present. The cornea 
is surmounted by a little tooth. 
The antennae are minute and filiform, and are completely exposed : 
their total length is not one-sixth that of the rostrum. 
The antennules are of large proportions: they fold longitudinally, 
but when folded are much beyond the capacity of the narrow shallow 
antennulary fossae. 
The external maxillipeds have broad endopodites, and completely 
cover the buccal frame: the merus is expanded in both directions, but 
most at its internal angle, so that the flagellum is inserted nearer to the 
external angle.
