In my Report on the Podophthalmous Crustacea of the Mergui-Archipelago, published in 

 [888, six specimens, 3 males and 3 females, of unequal size were referred by me to A. minor 

 Say var. neptunus Dana. Two of these specimens, a male and an ova-bearing female, both 

 1 7 mm. long, preserved in my private collection, are lying before me. It was on these specimens 

 from the Mergui-Archipelago that Syn. neomeris was founded by me in 1S97 (1. c). In this 

 paper 9 other specimens of smaller size, collected by Capt. Storm on the coast of Atjeh, 

 were also referred by me to this Syn. neomeris, but, as I now see, erroneously, for this Atjeh 

 form, specimens of which are also lying before me, proved after a careful examination to belong 

 to another species, viz. to Syn. streptodactylus Cout. In this paper of 1897 the figures 61a (large 

 chela of the male), 6id (third leg of the male) and 61e (dactylus of this leg) are relative to 

 the true Syn. neomeris, but the figures 61, 6iö and 6 ir to Syn. streptodactylus. Many an author 

 has probably been misled by this figure 61, which indeed does not represent Syn. neomeris. 

 According to my description of 1888 the second antennular article should be "scarcely longer 

 than the i st "; in the typical male of Syn. neomeris, the cotype, that is lying before me, the 

 second article, 1 mm. long and 0,6 mm. thick, appears a little shorter than the visible part, 

 long 1,1 mm., of the hrst article, but in the female this visible part appears just as long as 

 the second article, namely 0,9 mm. In all the specimens, collected by the "Siboga", the second 

 article appears also a little shorter than the visible part of the first, the proportion is, 

 however, somewhat variable. So, e. g., in the male from Stat. 299 the second article is one- 

 fourth shorter than the visible part of the first, in the adult male from Stat. 99 one-sixth and 

 in an ova-bearing female from Stat. 258 one-seventh. In all the specimens the third article is 

 distinctly shorter than the second. The stout stylocerite, the outer margin of which is setose, 

 reaches almost to the middle of the second article, as e. g. in an adult, ova-bearing female from 

 Stat. 164; sometimes it extends just to the middle, as in the male from Stat. 299, or even 

 slightly beyond the middle, as in the adult male from Stat. 99. In the two cotypes from the 

 Mergui-Archipelago the stylocerite extends also to just beyond the middle of the second article. 



The lower spine of the basicerite is turned outward at the tip and shorter than the 

 stylocerite, but it reaches more or less beyond the apex of first antennular article; the length 

 of the upper spine is one-third that of the lower. Carpocerite much longer than antennular 

 peduncle, projecting with the whole length of third article beyond the tip of this peduncle; 

 terminal spine of scaphocerite as long as the antennular peduncle, rounded tip of the blade 

 extending to the distal third, or sometimes to the middle, of third article.
