Subfamily Carotins.

15. Carupa ljeviuscula Heller, 1862. 



Carupa Iceviuscula, Heller, Verh. zool.-bot. Ges. Wien, xii. 

 p. 520 (1S62) ; id. ' Novara ' Crust, p. 27, pi. iii. fig. 2 (1868) ; 

 Alcock, Journ. As. Soc. Beng. lxviii. 2, i. p. 26 (1899).

Subfamily Portunito:. 

 Genus Neptunus de Haan, 1833. 



Neptunus, de Haan, Faun. Japon., Crust, p. 7 (1833) ; Alcock,

 (1897) ; id. Proc. U.S. Nat. Mus. xxii. p. 289 (1900). 



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

 genus proposed by Miss Batbbun. 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) granulatus (H. M.-Edw.), 1834. 



Lupea granulata, H. M.-Edwards, H. N. Crust, i. p. 454 (1834).

 (1899).

Subfamily Thalamitin-s:. 

 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 Thalamita 

 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.
