Species of Maioid Crustacea. 23 



Var. granulosus. 



Carapace considerably broader than long, granulated above, 

 the granules closest upon the surface of the branchial, gastric, 

 and cardiac regions. Antero-lateral margins with about a 

 dozen small obtuse teeth, followed by a very long acute spine, 

 to which succeeds a shorter spine on the back of each of the 

 branchial regions ; the posterior margin of the carapace be- 

 tween these spines is granulated. Rostrum triangular, not 

 deflexed, and minutely granulated on its lateral margins. 

 Anterior legs elongated ; arm with about five long spines on 

 its posterior margin, alternating with very small spines, with 

 about four tubercles on its upper surface, in a longitudinal 

 series, and twelve to fourteen unequal tubercles on its anterior 

 margin ; wrist granulated above, and with four or five spines 

 on its posterior margin ; hand with about six long spines, 

 alternating with smaller ones, on its posterior margin, with 

 about four distant tubercles in a longitudinal series on its 

 upper surface, and nine or ten spines on :ts anterior margin, 

 increasing in length toward the distal extremity ; the under 

 surface of arm, wrist, and hand is nearly smooth. Length of 

 carapace to base of rostrum 5 lines, breadth 6 lines. 



Hob. Philippine Islands, Corregidor (Cuming). 



The specimens described above have been referred by 

 White, in the ' List of Crustacea in the British Museum,' 

 p. 12 (1847), to L. serratus, M. -Edwards ; but they differ in 

 nearly all the characters mentioned in his brief diagnosis. 

 They are much more nearly allied to the typical Lambrus 

 hoplonotus of Adams and White, and may, indeed, be the 

 young of that species, but differ in the much smaller granules 

 of the carapace, and much fewer tubercles on the upper sur- 

 face of the hands. In both varieties the margins of the cara- 

 pace and anterior legs are clothed with close long hairs. 



Var. longioculis. (PI. V. fig. 6.) 



This variety is allied to the preceding and to the typical 

 L. hoplonotus ; but the tubercles of the carapace and of the 

 upper surface of the anterior legs are much longer, and, like 

 the teeth of the antero-lateral margins, tend to become veri- 

 table spines. The lateral epibranchial spine is relatively 

 much shorter than in L. hoplonotus. The rostrum is perfectly 

 smooth above and upon the lateral margins. The eyes are 

 remarkably long for a species of this genus, and project 

 beyond the orbits, the outer margins of which are deeply sui-
