 M.Sc, Research Assistaiit, Zoological Survey of India. 



vSince the memoir on Indo- pacific Stomatopoda was published 

 ii: 1913 ' a considerable number of specimens have been added to the 

 collection of the Zoological Survey of India. The majority' of these 

 belong to species already known to be abundant on the Indian coasts 

 and, as the records add nothing to our knowledge of their geographical 

 range, we have not thought it necessary to mention them There 

 remain, however, a number of other specimens interesting from the 

 point of view of their structural peculiarities, rarity, or distribution, 

 together with examples of two species which have not hitherto been 

 recognised. We have included a note on certain Californian speci- 

 mens of Gonodactyhis , which have kindly been lent to us for ex- 

 amination by Prof. Ch Gravier of the Paris Museum. These speci- 

 mens prove to belong to G. oersfedi, hitherto known only from the 

 Atlantic, thus adding greatly to our knowledge of the geographical 

 range of the species 



Caiman'^ has recently drawn attention to the importance of the 

 number of epipodites on the thoracic limbs as a specific criterion 

 in the genus Sqinlla and has given a key to certain Atlantic species 

 in which the primary divisions are based on this hitherto unnoticed 

 character. We find that the epipodites vary in the Indo-pacific 

 species also and we have thought it advisable to examine all the 

 forms represented in the collection and note the number present in 

 each. It is only in the genus Sqiiilla that any variation in the 

 number of epipodites is to be found ; in all species of Pseiidosquilla, 

 Hemisqiiilla, LysiosquiUa, Odontodactyliis and Gonodaciyliis that we 

 have examined epipodites occur on all the first five thoracic limbs.' 



Epipodites are to be found on the first five thoracic limbs in 

 the following species of Sqiiilla : —
