As Pandalus, except that the integument is thicker, and the eyes are very 

 small their diameter being less than that of the eyestalk and have no ocellus. 



As in lleterocarpiw, Chlorotocus and rirxiunilea, &c., the external maxilli|H'd< 

 have an exopodite (which is larger in Dorodotes than in any other Pandaloid), 

 and the scaphognathite is short, broad and rounded; and, as in all except 

 Parapwndalus, lliere are epipodites on all the thoracic legs except the last. 



The branchial formula is exactly the same as that of Pandalua, Chlri' 

 and Heteroearpus ; that is to say, there are epipodites to the first 7 thoracic 

 appendages, a podobranch on the 2nd maxillipeds, two arthrobranchs to the 

 external maxillipeds and one to each of the next four somites, and a pleuro- 

 branch on each of the last 5 somites in all, 12 branchia3 and 7 epipodites on 

 either side.

Dorodotes rejler.uf, Spence Bate, Challenger Crust. Macrara, p. 678, pi. crvi. fig. 3 : Wood-Mason, Ann. Mag. 

 Nat. Hist., Feb. 1891, p. 195. 



Rostrum about half as long as the carapace proper, much compressed, very 

 broad at base and acute at tip, ascendant and nearly straight, 5-7-serratf 

 ventrally, 5-6-serrate dorsally, where it is continued backwards beyond the 

 gastric region as a high compressed 8-9-serrate carina. 



Except for this serrated carina and for a small orbital and branchiostegal 

 spine, the carapace is smooth, and in life very greasy. 



Abdomen moderately compressed, smooth, non-carinate ; the 3rd tergum 

 has a very strongly convex, but not acute, posterior border. The 6th tergum is 

 not much longer than the 5th : the telson is a little longer than the 5th and Oth 

 combined, and its spines are strong and erectile. 



Eyes very small, but well pigmented, not so broad as the eyestalks. 



The antennular peduncle reaches more than halfway along the antennal 

 scale : its scale is compressed and acute, and reaches slightly beyond the 1st 

 joint, which is the longest : the antennular flagella are much longer than the 

 combined carapace and rostrum. 



Antennal scale about half as long as the carapace and nearly 3 times as 

 long as broad : the midrib is stout and the outer border is broadly thickened and 

 ends acutely. The usual spine is present at the far end of the outer surface of 

 the 2nd joint of the antennal peduncle. 



The external maxillipeds, which reach to the tip of the antennal scale and 

 have their terminal joint dorsally spiuose, are longer and much stouter than the 

 1st pair of legs.
