Mr. E. J. Miers on Malaysian Crustacea. 371 



nent and tuberculiform ; extraorbital tooth obsolete, infra- 

 ocular similar to the supraocular tooth. Antero-lateral mar- 

 gins 6-toothed ; the teeth rather small and tuberculiform ; 

 the two anterior somewhat approximated and placed at some 

 distance behind the orbits ; the two next teeth are similarly 

 approximated, and placed near the fifth tooth. No spines on 

 the subhepatic and pteiygostomian regions ; a low tubercle at 

 the antero-lateral angles of the buccal cavity. The legs are 

 closely pubescent ; the anterior legs (in the female) rather 

 robust, there are two tubercles on the outer surface of the 

 carpus, and the calcareous dactyli are regularly and evenly 

 toothed on their inner margins. The antepenultimate joints 

 of the second and third legs are somewhat dilated distally ; the 

 fourth and fifth legs present nothing remarkable. The sternal 

 sulci (in the female) are approximated, and terminate in a 

 strong tubercle situated in the space between the first and 

 second legs. The ridge on the endostome or palate is 

 partially interrupted. Length 2 inches 4 lines, breadth 2 

 inches 6 lines. 



Indo-Malayan Seas (a female without definite locality). 



From the Dromia Rumphii of Fabricius, to which it has 

 much external resemblance, this species is distinguished by 

 the form of the sternal sulci in the female, and by the disposi- 

 tion of the teeth of the antero-lateral margins ; the latter cha- 

 racter also serves to distinguish it from all the species referred 

 by Stimpson to the genus (or subgenus) Dromidia. 



Paguxidea. 



Birgus latro (Linn.). 

 Malaysia (an adult male of large size). 



Coenobita clypeata (Fabr.) . 



Amboina (an adult male) . The larger hand is nearly of 

 the form figured by Dana as characteristic of the variety he 

 designates brevimana, but is tuberculate externally, as in the 

 form he considers to be the typical clypeata.
