could be felt. The carapace is very stout, with the hinder peraeo- 

 pods contiguously paired beneath. The first peraeopods are very 

 slender, with the wrist 14 mm. long, twice as long as the chela, 

 the fingers of which are longer than the palm. The second 

 peraeopods are both detached, one imperfect, but the remainder 

 like its companion, these limbs being dark in colour, with none of 

 the joints dilated, but the palm rather stouter than the wrist, that 

 with the end unbroken measuring 126 mm. for the last 5 joints, com- 

 posed as follows, beginning with the 3rd joint, 15, 24, 33, 54, 27 mm., 

 the last of them, the finger, not adding to the length, as it closes 

 accurately over the thumb which equals the palm in length and forms 

 a very obtuse angle with it. The third, fourth, and fifth peraeopods 

 are subequal, but the fifth rather the longest, all extending beyond 

 the scale of the second antennae. The flagellum of these antennae 

 attains a length of 153 mm., the longest flagellum of the first 

 antennae (perhaps a little imperfect) measuring 118 mm. The 

 uropods extend a little beyond the telsou, and their exopod a little 

 beyond the endopod.

The present species may be regarded as a link between 

 P. viacrobracliion, Herklots, and P. soUatidii, de Man, 1912, on both 

 of which the latter author has bestowed so much accurate attention. 

 In the form here assumed to be new the rostral carina has 5 ventral 

 teeth, 9 dorsal, of which 2 are behind the orbit, and the foremost 

 3 are rather widely spaced ; the oblique apex is perhaps imperfect. 

 The carapace with rostrum measures 34-5 mm., the telson 10 mm., 

 the intermediate part about 35*5 mm., thus giving a total of 80 lum. 

 The slender first peraeopod is 34 mm. long. The right-hand second 

 peraeopod has a total length of 108 mm., the 3rd joint 14 mm., 4th 

 19 mm., 5th 35-5 mm., the 6th 39 mm. In the 6th the palm counts 

 for 25 mm., the thumb for 14 mm., the finger being only 13 mm. 

 does not quite reach the thumb's apex ; both are furred on their 

 opposed margins. The second peraeopod on the left is decidedly 

 shorter than its companion, the thumb (perhaps slightly imperfect) 

 not reaching beyond the finger. Both of these limbs can with 

 difficulty be seen to carry lines of microscopic prickles. The peduncle 

 of the first antennae does not reach the end of the scale of the second,
