20: 



Antennal scale narrow, as long as the antcnnular peduncle; outer marain straisfht, 

 terminal spine not or hardly reaching beyond the lamella; in Bate's figure of Proc. processa 

 (Report Challenger Macrura, Plate XCV, fig. c) the spine is much shorter, perhaps rudimentary. 

 Antennal peduncle a litde longer than the basal joint of that of the inner antennae, spine at 

 the antero-inferior angle of 2'"' joint very small. The antennal scale, which in this specimen is 

 3,84 mm. long, measures about three-fourths the length of the carapace without the rostrum 

 and one-fourth the length of the body. 



The e.Kternal ma.xillipeds (Fig. 52/) reach beyond the antennal scale by the terminal joint 

 and one-third of the penultimate; these two joints are of equal length, respectively 1,84 mm. and 

 1,8 mm. long, and together about one-fifth shorter than the antepenultimate. They resemble 

 the outer maxillipeds of Proc. processa (Bate) (I.e. Fig. i), but I would remark that in the 

 figure I / of this author the two joints appear together one-third shorter than the antepenultimate. 



The merus of the right chelate leg of the i^' pair (Fig. %2g) reaches to the middle of 

 the eyes; in a lateral view the carpus appears 2Y.,-times as long as thick at the distal extremity, 

 palm just as long as carpus, fingers one-third shorter. The merus of the left leg (Fig. 52//) is 

 slender, 8-times as long as broad, carpus a litde longer than one-third of the merus, 4-times 

 as long as thick at the distal e.xtremity, propodus half as long as the merus, almost 6-times as 

 long as broad pro.ximally, distinctly narrowing, dactylus almost one-third of the propodus. 



Of the right leg of the 2"'^ pair (Fig. 52 i) the merus extends to the far end of the antennal 

 peduncle and this leg projects by the chela and two-fifths of the carpus beyond the antennal 

 scale; it remained uncertain whether the merus is subdivided or not, the carpus, almost twice 

 as long as the merus, has about 20 articulations, that are longer than broad, those in 

 the middle twice as long as broad, the last segment almost twice as long as broad 

 and nearly as long as the two preceding together, that are but little longer than broad; the 

 chela measures almost one-si.xth of the carpus and is four- times as long as broad, fingers 

 hardly shorter than palm. Of the left leg of the 2"'> pair the merus reaches to the middle of 

 the eyes, while only the chela and the last joint of the carpus project beyond the antennal 

 scale; the proportion between merus and carpus is like 4:7, the merus probably subdivided; 

 the carpus has 15 segments, the i*' or proximal measures nearly one-sixth the length of the 

 joint and is 5-times as long as thick, the 3'''i 2Y.2-times as long as broad, those in the middle 

 one and a half as long as thick, the following relatively still shorter, the penultimate even a 

 little broader than long, the last segment one and a half as long as thick and as long as the 

 two preceding taken together; the chela measures one-sixth of the carpus and is 3-times as 

 long as broad, fingers slightly longer than palm. 



The following legs are wanting or incomplete; of those of the 3"' pair the merus reaches 

 as far forward as the i^' joint of the antennular peduncle and the merus of the 4''' pair extends 

 but little farther. 



The branches of the 2'"' pleopod are narrow, the inner little shorter than the outer; the 

 stylamblys with well-developed cincinnuli measures about one-fourth the length of the endopodite. 



At first I was inclined to refer this specimen to Proc. processa (Bate), but according to 

 B.vTF.'s figure / the carpal segments show a different form, being not or hardly longer than wide.
