a few short and fine hairs. The dactylus of the last pair has a 

 slight swelling at the base which is rather thickly clothed with 

 short hairs. 



The abdomen is much compressed laterally, but is not carinate. 

 The sixth somite, measured dorsally, is fully two thirds as long as 

 the carapace. The pleopods, as in L. tenuipes, are very long, those 

 of the first pair being nearly one and a half times the length of the 

 carapace. The telson is rounded above and bears a single pair of 

 dorsal spinules near the distal end. The apex is minutely pointed 

 in the middle with a long lateral spinule on either side.

The single specimen of this interesting species is a female, 

 without eggs. The rostrum and carapace together measure about 

 14 mm., the carapace alone being about 65 mm. Owing to the 

 fact that the specimen is strongly bent it is difficult to measure 

 the total length in a satisfactory manner ; it would probably be 

 about 32 or 33 mm. when the animal was extended. 



The type specimen (no. 9758/10, Zool. Surv. Ind.) was dredged 

 by Dr. Annandale in China, in the Whangpoo River between 

 Shanghai and Woosung, at a depth of 5^ to y^ metres. It was 

 obtained in water that was quite fresh.
