This Family is not represented in the collection here reported on; but as the distribution 

 of Triticella boeckii noted below gives sorae reason for supposing that it is not unlikely to 

 occur in the Malay region, a few notes on this species may not be out of place.

 Hippuraria egertoni Busk, 1874, 1. c. 



The genotype of Triticella is T. jïava Dalyell. A species of this genus had previously 

 been recorded by Gros 1 ), under the name of Phimatella familiaris, from Ostende and Havre; 

 and this specific name has been adopted by Smitt 2 ), for one of the species of the genus, 

 apparently identical with T. korenii Sars. 



Mr Waters 8 ) has made the following statement: - - "Hippuraria, Busk, has a delicate 

 "rhizome, from which groups of zooecia arise. In the only specimen (which is now in the British 

 "Museum) it is growing upon the stalk of a seaweed, and this was mistaken for the stem of 

 "■Hippuraria. There is, therefore, now absolutely no reason for separating Hippuraria from 

 " Triticella'. 



I agree with Mr Waters in his general conclusion, but from an examination of the type- 

 specimen (73. 11. 21. 1) of H. egertoni, to which he alludes, I have come to a different conclusion 

 with regard to certain details. The slide had suffered from the drying up of the medium in 

 which the specimen had been mounted; and it has been re-mounted by Mr Kirkpatrick since 

 Mr Waters examined it. It is now quite clear that the description "delicate rhizome" is
