The oral appendages do not differ noticeably from those of the 

 two preceding species. The third maxillipedes reach beyond the 

 end of the antennular peduncle ; the ultimate segment is less than 

 twice the length of the antepenultimate. 



In the chela of the first peraeopods the finger is about as long 

 as the palm. The second peraeopod reaches to the middle of the 

 rostrum. Of the three segments composing the carpus, the first is 

 scarcely half the length of the second and is a little longer than 

 the third ; the chela is as long as the middle segment and the 

 dactylus is shorter than the palm. 



The third peraeopods reach forward a little beyond the end of 

 the second and the fifth extend to the end of the eyes. The 

 dactylus in each of the last three legs consists of a strong curved 

 claw about one third the length of the propodus ; it may bear a 

 few microscopic spinules, but is otherwise wholly unarmed. 



Large epipods are present at the base of the first four pairs 

 of peraeopods. 



The sixth abdominal somite is more than one and a half times 

 the length of the fifth. The outer uropod is two and two -thirds 

 times as long as broad. The telson bears two pairs of dorsal 

 spinules and terminates in a narrow apex composed of a short 

 median process with two spines on either side ; the inner spine is 

 longer than the median process and nearly twice the length of the 

 outer (fig. 5). 



In the absence, in the majority of cases, of any information 

 regarding the spinulation of the dactyli of the last three legs, it 

 is difficult to make suggestions regarding the affinities of the 

 species described above. It appears to be most nearly related to 

 Ortmann's L. laminirostris , but differs from that, and apparently 

 from all other known species of the genus, in the form of the 

 rostrum. 



Bombay. Bombay Nat. Hist. Soc. One, ovigerous female, 



39 mm. TYPE. 



For the opportunity of examining the single known example 

 of this species I am indebted to the Secretary of the Bombay 

 Natural History Society.

Form extremely slender. Carapace without supra-orbital, but 

 with antennal spine ; a single spine at antero-lateral (ptery gostomian) 

 angle. Lateral process of antennular peduncle sharply pointed 

 anteriorly. Upper antennular flagellum uniramous. Mandible 

 without incisor-process or palp. Third maxillipede without exopod. 



1 Stimpson informs us that this name is derived from the Greek To^evfia, 

 but, if the spelling is emended, the name is preoccupied by \\'alker for a genus 

 of Hymenoptera.
