preceding joint, slender, 6,6 (6,2)-times as long as wide at the distal end; relative dimensions : 

 merus 1,75 (1,6); carpus i; propodus 0,96 (0,9). Carpus 4,4 (4,5)-times as long as broad, 

 presenting the same width almost along its whole length; propodus 6 (5,6)-times as long as 

 wide in the middle and gradually narrowing. Dactylus measuring three-elevenths (one-third) of 

 the propodus, 6 (5)-times as long as broad, much narrower than the preceding joint ; tip truncate, 

 with a tuft of setae. All the joints of this leg, excepting the dactylus, are fringed, along their 

 margins, with long, feathered setae, but they are quite unarmed. 



In the specimen from Stat. 102, which is the type of this species, the fifth legs are missing. 



The specimen from Stat. 3 1 3 may once prove to belong to a distinct species, but the 

 differences are perhaps owing to the younger age.' The rostrum, that appears hardly longer 

 than wide in the middle, is much short er than the extra-orbital angles. 



The eye-peduncles, very slender, 25-times as long as thick in the middle, are compa- 

 ratively longer than in the type specimen, measuring just two-thirds the length of the 

 carapace ; the eyes are one and a half, the base of the peduncles 3-times as thick or broad, 

 looked at from above, than the middle of the peduncle. 



The scaphocerite, that reaches a little beyond the middle of the eye-peduncles, shows 

 another form than in the other specimen, the outer margin, indeed, terminates in a distinct 

 spine at a right angle with the obtuse extremity of the scale. 



As was already remarked, the measurements of the four anterior legs are indicated 

 above in parenthesis and show that the joints are generally of a somewhat stouter form. The 

 chela of the first legs appears a little longer with regard to the carpus, but the second legs 

 resemble those of the type and, as in the latter, the chelae of these legs are just as long as 

 those of the first pair. The fifth legs are present and are quite characteristic : they are much 

 th inner and feebier than the two preceding legs. The ischium is elongate, very 

 slender, 15-times as long as thick in the middle and but little thicker at both extremities. 

 Merus much shorter than the preceding joint, the proportion being as 1 :o,Ó4; the 

 merus very slightly thickens distally and is 8-times as long as thick at the distal extremity. 

 The relative dimensions are: merus 2,5; carpus i; propodus 1,3. Carpus conical, 2,6-times as 

 long as thick at distal extremity. Propodus 3-times as long as wide in the middle and about 

 half as wide at either extremity as in the middle ; the arcuate, posterior margin with 5 or 6, 

 feathered setae. Dactylus hardly shorter than the propodus, 7-times as long as broad proximally 

 and slightly narrowing toward the distal extremity which is truncate and furnished with two 

 feathered setae, as long as the dactylus itself, while three other similar setae occur on the 

 lower margin. 



The type specimen from Stat. 102 is 18 mm. long, the other 12,4 mm.; the carapace 

 of the latter, rostrum included, is 3,9 mm. long, that of the type 5,5 mm. 



Automate de Man. 



The genus Atitomate de Man, established in 1888 for a species living in the Bay of 

 Batavia, is represented in this collection by a new species, remarkable by the propodi of the
