forms, as Jurich has done both in this case and in the case of Squilla minor, is greatly 

 to be deprecated. 



Wood-Mason's type specimen is the only example of L. multifasciata preserved 

 in the Indian Museum : — 



~ Bombay. Bombay Nat. Hist. Soc. i $ , 44 mm. TYPE. 



Balss has recorded the species from Formosa. Nobili's examples, which aire per- 

 haps wrongly determined, were found at Samarinda in Borneo and at Obock in the 

 Red Sea. The locality of Jurich' s L. valdiviensis is. unknown.

 This species, like the preceding, is a close ally of L. acanthocarpus , but differs from 

 it structurally in the following features : — 



1. The dactylus of the raptorial claw bears six teeth, including the apical one, and 



the penultimate is longer than the ante-penultimate. The lobes at the base of 

 the external margin have much the same form as in acantho carpus. 



2. There are only three pairs of denticles, which are comparatively large, between 



the mobile submedian spines of the telson. 



3. The rounded lobe fringed with long setae which is found in L. acanthocarpus 



on the ventral aspect of the basal segment of the outer uropod, projecting over 



the articulation with the ultimate segment, does not exist {fide Bigelow, fig. 



4) in L. biminiensis and the carina on the lower surface of the peduncular 



segment (which ends in a strong anterior tooth in L. acanthocarpus) also 



appears to be missing. 



The colour of the living animal, according to the full description which Bigelow 



gives, is fawn or pink with black, reddish brown and bright lemon yellow markings. 



The black colouring, which alone persists in alcohol, exists as a narrow border round 



the postero-lateral angles of the carapace. There is also a black posterior transverse 



streak on either side of the last thoracic and fifth abdominal somites and a pair of 



small black eyespots on the telson placed side by side in the median line just in front 



of the dorsal spines. 



The specimen which Borradaile names pacificus differs structurally from those des- 

 cribed by Bigelow only in the most insignificant features, but the colouring is different 

 for on each somite from the sixth thoracic to the fifth abdominal inclusive, there is a 

 narrow deep-black posterior border. 



Bigelow' s two specimens (48 mm. in length) were found in a burrow in the sand 

 at the Bimini Is., Bahamas, while the single individual which Borradaile records was 

 found at New Britain and is called pacificus in order to emphasize the remarkable 

 distribution of the species.
