Rem. Cette espèce se fait reconnaître aisément parmi ses voisines par les cercles blanchâtres 
des pores des mâchoires, par les taches jaunâtres au-dessous et en arrière de l’angle de la bouche 
et par la bordure jaune de la nageoire anale. Elle est voisine du Gymnothorax borneënsis, mais 
celui-ci n'a pas les taches blanches de l’espèce actuelle, ni la bordure de l’anale, tandis que la 
l'ente de la bouche y est notablement plus petite.

Descriptio Kaupiana sequens: 
„Nasal teeth 12; palatines 11—12 ; mandibulars 22, ail pretty well developed; vomerines 12, short, conical , and radier obtuse; 
disposed in an irregular row, in some places two-ranked. Tins species cornes near to Muraena similis, but differs in having 22 
teeth on the inaudible, and also in îts colour and markings. Eye round, pretty large, contained twice and a little more in the 
length of the elongated snout, and more remote from the tip of the latter than from the angle of the mouth. Dorsal originating 
before the gill-opening. Colour of the body dull brown , îighter on the lower parts ; behind and below the eye irregulary spotted 
with white. Pores of the upper jaw, and mandible, bordered with white. Hab. Archîp, Molucc. v. Malayan.” Kp.

Rem. Je n’ai pas retrouvé cette espèce au Musée de Leide, où M.- Ka up dit l'avoir observée. 
Je n’ai donc pu que transcrire la description peu complète de cet auteur. L’espèce me semble 
être voisine du Gymnothorax chilospilus Blkr, mais elle s’en distingue par sa dentition. Aussi me 
semble-t-elle insuffisamment établie et avoir besoin d'être étudiée de nouveau. Je ne l’ai insérée 
ici que pour mémoire. 
Gymnothorax thyrsoideus Blkr. 
Descriptio Cantoriana sequens: 
„The form of the body is compressed, of nearly juniform deptli. The length of the head to the gill-opening is contained from 7 ( / 2 
to 7 2/ 3 times in the total, or about 3*^ times in the distance from the muzzle to the anus. The horizontal diameter of the eye is 
i/ 10 to '/u of the length of the head; the distance across the forehead is P/ 3 diameter; the distance from the muzzle to the eye is 
two such; tbat from the muzzle to the angle of the mouth is about i/ 2 of the length of the head. The anterior apertures of the 
nostrils open through two small tubes, situated on each side of the muzzle, at a distance from one another of one diameter of the 
eye. The posterior apertures are small, oral, with a narrow membranous edge; each is placed above the fore part of the orbit. 
On the upperlip appear on each side four distant pores, and on each side of the lower lip four similar ones. Both jaws are of 
nearly equal length and arrned with two sériés of teeth. Those of the outer sériés are minute, yet strong, pointed with trenchant 
edges, and the sériés of both sîdes are uninterrupted on the symphysis of the upper jaw. Those of the inner sériés are more dis- 
tant, thicker and longer. On the mesial line of the upper jaw appear four or five longer, distant, subulate teeth, which gradually 
increase in length, and are moveable, The rest of the mesial teeth are minute subulate, lieaded by one longer than the rest, which 
are at first placed in a double, but terminate in a single sériés. Neither tongue nor latéral line are distinguishable. The vertical 
diameter at the occiput is contained 2>/ 2 times in the length of the head. The anus is situated half the length of the head behind 
the middle of the total length. The gill-opening is small, oval and placed obliquely , nearer the abdomen than the back. The 
dorsal commences three diameters of the eye in front of the gill openings. The rays increase in length towards the posterior half 
of the tail where they are */* of the length of the head. The caudal is but ] / 7 of the head and so closely attached to the dorsal 
and anal that its origin can not be dîstinguished. The anal commences a little behind the vent; it resembles the dorsal. — Head, 
body and fins of darker or Iighter pitch colour, so closely and fincly marbled and dotted with white or yellowish white, as not to 
affect the general dark colour; abdomen Iighter than the rest of the body. Iris pale golden, minutely dotted wich black. B. 9. 
D. C. A. 569 to 611. — Total length 2 feet 2 inch. — Single individuels occur at al seasons at Pinang.”
