The following brief criticisms may be made respecting 

 Prof. Kraepelin's determinations of tiie species of this 

 genus : — 



Diphcentrus Hasefhi, Kraepelin (Jahrb. Hamb. Wiss. 

 Anst. xiii. p. 130, 1896), from Cnra(jao, is closely allied to 

 1). antillamis, Poc, not to D. Whitei, Gervais; but, judging 

 from the description, it differs in having the vesicle granular 

 and the caudal keels better developed. 



Diphcentrus Whitei, Kraepelin (Jahrb. Hamb. Wiss. 

 Anst. xi. p. 13, 1894), is not the same as Whitei of Gervais, 

 whatever else it may be. Prof. Kraepelin quotes D. mexi- 

 canus, Peters, and 7). Gundlachi, Karsch, as undoubtedly syno- 

 nymous with it, and Oiclus Purves>\ Becker, and D. Keyser- 

 lingii, Karsch, as doubtfully so. So far as Oiclus Purvesi is 

 concerned, this view is quite untenable. The British 

 Museum has recently received from Mr. Forrest specimens 

 of the latter species from Antigua, and I have been able to 

 establish the accuracy of Mons. Simon's observations as to 

 the ])resence of but two lateral eyes on each side, the feature 

 upon which the genus Oiclus was based. In addition to this 

 the species is characterized by sundry well-marked specific 

 features, sufficient, apart from the eyes, to differentiate it 

 from all the members of the genus Diplocentrus known to me. 



Diphcentrus anfiUanus, Kraepelin {he. cit. p. 16), is not 

 identical with D. antilhnus^ Pocock, but is either the same 

 as, or closely allied to, D. Jlhitei, Gervais, and D. rectimanuSy 

 Poc.
