Mr. E. J. Miers on new Species of Crustacea. 341 



XLV. — On some new or undescribed Species of Crustacea 

 from the Samoa Islands. By Ed WARD J. MlERS, Zoolo- 

 gical Department, British Museum. 



The species of which descriptions are here given form part of 

 a large series collected by the Rev. S. J. Whitmee, who is 

 at present resident in the Samoa Islands, and presented by him 

 to the Trustees of the British Museum. The collection con- 

 tains in all nearly fifty species ; and many of the specimens 

 are remarkable for the beauty of their colouring ancl the ex- 

 cellence of their preservation. 



Chlorodius samoenstSj sp. n. 



Carapace regularly arcuate in front, strongly areolated, with 

 deep longitudinal grooves, and with a strongly marked trans- 

 verse line extending across the carapace to the base of the fifth 

 tooth on either side. Latero-anterior margins with five small, 

 equal and equidistant teeth (the external orbital angles in- 

 cluded) ; .front prominent, four-toothed (the internal orbital 

 angles excluded). Anterior legs granulous externally ; wrist 

 with two small tubercles ; hand with a single small tubercle 

 on its upper surface, close to the articulation with the wrist ; 

 mobile finger with a small tubercle at its base. Ambulatory 

 legs short, very hairy. Colour greenish grey ; fingers brown, 

 the brown colour extends a little over the lower part of the 

 hand. 



Length f inch, width £ inch. 



Hob. Samoa Islands. 



This species is closely allied to the Chlorodius dentifrons 

 of "Stimpson (Proc. Acad. Nat. Sci. Philad. 1858, p. 34), from 

 Loo-Choo ; but it differs in the sculpture of the anterior legs, 

 which in C. dentifrons have two or three small teeth on the 

 wrist and three or four on the hand. 



Thalamita speciosa, sp. n. 



Carapace transverse, covered with a uniform short close 

 pubescence ; the transverse ridges, the margins of the frontal 

 lobes, and the teeth of the antero-lateral margins naked. 

 Front divided into eight teeth, separated by rather deep 

 fissures, the two median equal, truncated at the extremity : 

 the next two on each side unequal, rounded at the extremity ; 

 the external tooth on each side very broad, with the inner 

 margin arcuate, and separated from the next inner tooth by 

 a very wide fissure. Latero-anterior margins with four equal 

 teeth. Basal joint of the external antenna? with a series of
