spinule on the inner side of the tooth that terminates the straight 

 or slightly convex outer border. 



Large specimens reach a length of about 60 mm. None of 

 the females in the collection are ovigerous. 



Young examples, from 15 to 25 mm. in total length, differ from 

 adults in possessing a shorter rostrum, often not reaching beyond 

 the end of the antennular peduncle and in the proportionately 

 greater length of the sixth abdominal somite. 



The colour of living specimens was translucent white, with 

 sparsely scattered minute reddish-brown pigment cells, not ar- 

 ranged to form a definite pattern. 



L. modesius is very closely related to L. mani, Sollaud,^ from 

 Tonkin, a freshwater species described as possessing large eggs. 

 The most conspicuous character in which L. modesius differs from 

 the southern Chinese form is the complete absence of teeth at the 

 distal end of the upper border of the rostrum, a feature which is 

 unquestionably of high specific value in other species of the same 

 group of the genus. The first maxillipede differs from the figure 

 given by Sollaud in the greater proportionate length of the basi- 

 podite, while the distal lobe of the epipod, though apically pointed, 

 is not drawn out to the triangular process to which Sollaud has 

 directed attention. The description of L. mani is preliminary ; 

 other distinctions will probably be found when the full account 

 is pubhshed. 



The specimens of L, modesius in the Indian Museum were all 

 obtained by Dr. Annandale in China, in the neighbourhood of Shang- 

 hai. The species is common at the margins of the Tai Hu Lake, 

 and is caught in large numbers in basket traps set among weeds. 

 A few individuals were dredged from a bare muddy bottom in the 

 middle of the lake and others were obtained in the Whangpoo 

 River, between Shanghai and Woosung at depths of Si to /I metres. 

 Young examples are common in ditches and ponds in the neigh- 

 bourhood of Shanghai. All the specimens were obtained in pure 

 fresh water. 



The species was described by Heller from Shanghai in 1865, 

 since which date it does not appear to have been recorded. 



Leander fluminicola, sp. nov. 

 (Plate ix, fig. 2.) 



This species bears a close general resemblance to the preced- 

 ing, differing from it only in the following particulars: — 



(i) The rostrum exceeds the antennal scale by one sixth or 

 one quarter of its length. The basal crest is less elevated and bears 

 from 7 to II teeth (usually 8 or 9) ^ of which i or 2 are placed 

 behind the level of the orbit. The distal part of the rostrum is

 three have 9, three have 10 and one has 1 1.
