the fourth and fifth joints (Fig. 49 b), as the longest segment sometimes has a sUght 

 constriction near the distal end but never any trace of a suture. 



Oviger. The ovigers are hidden almost completely by the two clusters of larvae ; one 

 from another male is represented in Fig. 49 a. 



Third leg. Second coxa rather longer than the sum of the first and third. Femur 

 subequal to first and a little shorter than second tibia ; approximately six times as long 

 as wide. Terminal segments as represented in Fig. 49 a ; similar in all four legs. Setules

restricted almost entirely to the dorsal surface of the longer segments, with a single 

 row on each lateral and ventral surface. The genital openings are present on the second 

 coxae of oil four legs. 



The female, apart from the usual sexual differences, agrees with the male. The femur 

 is only four times as long as wide. 



Remarks. The smaller specimens from St. 5 1 (measuring 6-6-8 mm. in length) all 

 have conspicuous genital openings, but the fingers of the chelae are rather longer than 

 in the holotype and the legs are relatively shorter and stouter. There are four pairs of 

 genital openings in each male specimen ; in the other species of Ammothea the genital 

 openings are only present on the second coxa of the last two pairs of legs. 



This species agrees with A. longispina, n.sp., in the number of palpal segments, but
