Four fine specimens were collected in the Mergui Archipelago, 

 viz. an adult male and three younger males. 



One of the latter was sent by me successively to Dr. Hil- 

 gendorf, of Berlin University, and to Prof. A. Milne-Edwards, 

 in order to attain accuracy in naming these specimens. Dr. 

 Hilgendorf informed me that it belonged to his Myomenippe 

 duplicidens^ whereas Prof. Milne-Edwards stated that it was 

 a representative of bis Menippe granulosa. The latter name 

 has the priority, as it was established eleven years before tbe 

 former. Dr. Hilgendorf moreover mentioned to me the charac- 

 ters by which this species may be distinguished from Menippe 

 Panope, Herbst, whicb is a true Menippe, and from Menippe 

 MumpMi, Eabr., wbich is identical with Menippe Belangeri, 

 M.-Edw. 



As Myomenippe granulosa, A. M.-Edw. { = duplicidens, Hilg.), 

 is still insuflSciently known, I will describe the largest specimen. 

 The upper surface of the cephalothorax is rather convex, and 

 the regions are very distinctly indicated, being separated from 

 one another by rather deep interregional grooves. The elevated 

 parts of the upper surface are covered with numerous very dis- 

 tinct granules, and the postero-lateral regions of the cephalo- 

 thorax are also granular. The front is divided into six teeth, of 

 whicb the two, most prominent, median or first teeth are much 

 broader than the two lateral of each side ; the median teeth are 

 truncate anteriorly, whereas the two lateral teeth are tuberculi- 

 form, the third tooth being even a little smaller than the second. 

 Immediately behind the second teeth, and on each side, a granu- 

 lated, small, rounded tubercle is found. The front is separated 

 from the orbits by a fissure, which is broader and deeper than the 

 fissure between the second and third frontal teeth; behind the 

 former fissure the terminal joint of the peduncle of the external 

 antennae is visible — that is, perfectly excluded from the orbits. 

 The internal angle of the granulated upper margin of the orbits 

 is rather obtuse, extends less forward than the frontal teeth and
