CAPRELLID^E. 227 



Finally, the penultimate joint of the palp of the maxilliped (fig. 6) is produced into 



a pointed process, which appears to he occasionally ahsent, and, at any rate, affords 

 no easily distinguishable characteristic. 



The length of the male is about 8'5 millims.. that of the female not <piite 4 millims. 

 Dorsal surface of body smooth, save that the second segment in the male may bear a 

 pair of very small tuhercles anteriorly (fig. 1). Laterally, on segments 2 to 4, short 

 ridges are present anteriorly, which in the female project less strongly, just as in 

 .1/. agilis. First antenna short; flagellum in the male with 9, in the female 

 with S joints. Second leg short ; arm thin, joints 2 and 3 with a short lateral 

 ridge, which in the old male (fig. 2) is relatively small ; joint 4 round. The hand 

 of the male is long, slender and sickle-shaped, its palmar edge covered with long 

 bristles; in females and young males (figs. 4 and 3) it is relatively broader and not 

 sickle-shaped; the locking spine is proximal, the poison-tooth distal, the claw is long. 

 Gills long and slender ; the corresponding legs very small in the old males, in the 

 females and young males (figs. 8 and 7) relatively larger and less pointed. Leg 5, in 

 place of the locking spine, has one or two somewhat strong hairs ; legs 6 and 7 have 

 one (exceptionallv, in old males, two, one after the other) locking spine which is 

 obliquely truncated. 



The mandibular palp in the old males has at the end of the third joint a palette 

 and 1 long, 3 small, and 2 middle-sized hairs (studied in situ,). I give a figure of that 

 of a not cpiite adult male (fig. 5) and also of the maxilliped (fig. 6). The first maxilla 

 hears on its outer plate 7 hairs. 



A profile-view of the abdomen of the male is given in fig. 9. 



I am not quite certain whether to this species belong some small and badly 

 j;ireserved specimens from the following localities : Pearl banks oft' Aripu (1 female); 

 Muttuvaratu pearl oyster washings (1 female with two large eggs in the brood- 

 pouch); and East Cheval Paar, 6 fathoms (1 young female).
