268 ZOOLOGY OF THE FAR EAST. 



The series includes several ovigerous females, each bearing a great number of very 

 small eggs. 



Palaemon lampropus is known to occur in Celebes and Timor and has been recorded 

 by lyanchester from Aring in Kelantan. The number of dorsal teeth on the rostrum 

 in lyanchester's specimens (12 or 13) is considerably lower than in any of those found 

 by Dr. Annandale. 



Genus Leander, Desmarest. 



In a recent paper in the Records of the Indian Museum I have revised the 

 section of this genus that comprises Milne-Edward's Leander styliferus and related 

 forms. This paper contains descriptions and figures of three of the five species 

 obtained by Dr. Annandale in the course of his tour. 



Leander annandalei, Kemp. 



1917. Leander annandalei, Kemp, Rec. Ind. Mus., XIII, p. 211, text-figs. 1-4. . 



This remarkable species is based on a single individual dredged in the Whangpoo 

 River, between Shanghai and Woosung, at a depth of 5|- to 7J metres. It was 

 found in pure fresh water. 



Leander annandalei is particularly interesting in that it forms a link between 

 L. tenuipes, Henderson, in which the last three pairs of legs are excessively long and 

 filiform, and more normally constituted species of the genus. 



Leander modestus, Heller. 



1917. Leander modestus, Kemp, Rec. Ind. Mus., XIII, p. 221, pi. ix, fig. i. 



From material obtained by Dr. Annandale at Shanghai I have been able to draw^ 

 up a fresh description of this species, which was hitherto known only from the account 

 given by Heller more than fifty years ago. 



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 5|- to y^ metres. 

 Young examples are common in ditches and ponds in the neighbourhood of Shanghai. 

 All the specimens were obtained in pure fresh water. 



In redescribing this species I unaccountably omitted to notice that Henderson in 

 1893 recorded Leander modestus from Madras. I have recently obtained from 

 this locality specimens of a form which is without doubt identical with that examined 

 by him. The specimens are, in my opinion, to be referred to L. semmelinkicf a species 

 which in many respects bears a close resemblance to L. modestus.
