The 2nd pair arc nearly as long as the entire body, the chelae and carpus 

 and more than half the mcrus lying in front of the antennal scale. 



The last three pairs are very much longer than the entire body, the two 

 short terminal joints and the elongate carpus and two-thirds of the elongate 

 merus lying in front of the antennal scale. 



Colour in life red. 



In an egg-laden female the length of the rostrum is 8 millim., of the 

 carapace - 2:! millim., of the abdomen 03 millim., of the longest leg 130 millim. 



Arabian Sea, in the neighbourhood of the Laccaclives and south-eastwards, 

 in 459, G36, and 705 fathoms. 



This species may perhaps be only a variety of A', i-urxnr, from which it 

 only differs (1) in having more teeth on the dorsal edge of the rostrum, and (2) 

 in the greater length of the legs, especially of those of the 1st pair.

Rostrum well developed. Antennular scale present. Antennal scale long 

 and narrow. Two antennular flagella. 



Mandible deeply cleft into strong incisor and molar processes, and bearing 

 a palp which usually consists of 3 segments. The 1st and 2nd maxilla,' and 

 the 1st maxillipeds have the coxa and basis well developed, but the coxa of the 

 2nd maxilla3 recedes. The exopodite of the 1st maxillipeds ends in the usual 

 flagellum. External maxillipeds pediform, stout, with, or without an exopodite. 

 The terminal segment of the 2nd maxillipeds is a narrow plate attached along 

 all its extent to the inner border of the penultimate segment, as it' it \veiv a 

 complements! piece of the latter segment. 



The first pair of legs are slender and are- usually said to be inonodaetylous 

 but, as Caiman has shown, they very often end in a microscopic and more < >r 

 less imperfect chela. The second pair of legs are minutely chelate. The thoracic 

 legs never have exopodites. 



Eggs small and numerous. 



Numerous genera of this family have been proposed, but it seems to me 

 that they may all be resolved into the following five, and the distinctions bet ween 

 even these are extremely slight : 



1. J.'<in<lI/t*, Leach, with subgenera /V,M//J/I^X/.-, P/^innU.-n (=also 

 Nothocaris) and Parapa/ndalus.
