NO. 3589 GENUS MANNINGIA — MANNING 9 



Color. — The color pattern is completely faded in the USNM spec- 

 imen, but some chromatophores are visible on the one from the British 

 Museum. There are dark chromatophores along the abdominal 

 pleura, with the ventral margin of each pleiu-on black; the anterior 

 edge of the merus of the claw is black; and the posterior margin of 

 the carapace, last abdominal somite, and telson are outlined in dark 

 pigment. 



Measurements. — Summarized in table 1. 



Discussion. — The presence of the following features will distinguish 

 M, 'pilaensis from the other species of the genus: (1) a slender rostral 

 spine; (2) one mesial and one ventral papilla on the antennal protopod; 

 (3) the inferodistal spine on the merus of the raptorial claw; and (4) 

 the uninterrupted intermediate carinae of the telson. M, pilaensis 

 agrees with M. notialis and differs from M. serenei, new species, as well 

 as the undescribed species from the Gulf of Aden in lacking a rounded 

 lobe between the spines of the basal prolongation of the uropod. 



Although de Man (1888) did not illustrate the type, from Elphin- 

 stone Island, Mergui Archipelago, he did provide a long and detailed 

 description with which the present specimens agree in all respects. 



Remarks. — The specimens available differ in minor details of telson 

 ornamentation, particularly in the numbers of subterminal tubercles 

 and spinules on the submedian and intermediate dorsal carinae. On 

 the USNM specimen, the right lateral carina recurves anteriorly and 

 terminates in a spine; on the left side a short, spined carina is present 

 in the same location, but it is not connected to the lateral. The left 

 intermediate spine of the sixth abdominal somite is bifurcated on the 

 USNM specimen. 



Distribution. — M. pilaensis is known from the two specimens 

 from Amoy, China, discussed herein, and from two other specimens 

 collected at Elphinstone Island, Mergui Archipelago, eastern Indian 

 Ocean.

 along midline.
