I am unable to agree with the alteration of the name of this 

 genus proposed by Miss Kathbun. On the subject of Latreille's 

 " types " 1 am in full agreement with the position taken up by 

 Stebbing (Nat. Sci. xii. p. 239). 



16. Neptunus (Achelous) granulatcs (H. M.-Edw.), 1834.

Subfamily Thalamitin.*:. 

 Genus Thalamita Latr., 1829. 



17. Thalamita prymna (Herbst), 1803. 



Cancer prymna, Herbst, Naturges. Krabb. u. Krebse, iii. 3, p. 41, 

 pi. lvii. fig. 2 (1803). 



Tlialamita prymna, H. M.-Edwards, H. N. Crust, i. p. 461 

 (1834) ; Alcock, Journ. As. Soc. Beng. lxviii. 2, i. pp. 76, 78. 



Alcock supports Kossman's view that all the forms of Tlialamita 

 with an eight-lobed front and a very broad basal joint to the 

 antenna are but varieties of one species {T. prymna). The present 

 collection contains no examples of the type, but three varieties are 

 represented.
