(as is also the case in the lu'ccedint;- and following ossicle). Between 

 I Bi- 1 and 2 a close articulation. Axillary li = ^4 br, without a late- 

 ral tlange. II Br — s: 2. Arms XII, W nun. Priinip(»staxillai-ies basally 

 united inside. Br 2 on the outside twice as broad than on the inside. 



Ex. of syzygies: 8 -r 4, 12+13, 17 + 18, 21 + 22.. etc. with 

 an interval of 3 to 4 oblique articulations. 



P, 19: 4,.-; mm. (the 2 first segments strongly enlarged. I'*' seg- 

 ment h = ' 3 br with a wing which is broader than the br of the seg- 

 ment, 2'' segment h = ' 2 br with a smaller wing, the following seg- 

 ments slender h = 1' 2 br, rather smooth, though angular). H.^ 17; 7 mm. 

 coarser than 1\ (P' and 2'' segments as in P, but more slightly alated. 

 8' and the following segments L = 3 — 4 X br, distal segments shorter, 

 with small distal, spiny whoi'ls). P, 10; 5 mm. (only the l'"' segment 

 with a wing). A wing on the P*^ segment more and more inconspi- 

 cuous out to P,,, or Pj.. Distal p. 15; 7 mm. (P* and 2'' segment a 

 little enlarged L='2 — ' 1 br, 3'' and following segments L = 2 — 2' '2 

 br. Last 4 segments shorter and more delicate, with distal, spiny 

 whorls). Disk thrown off. Ectoparasitical Enlima. 



Sp. 2 (St. 12) C. X 28 — 31, + 11 mm. A dorsal spine from the 

 12"' segment. 



The R — s IK pi'ojeeting. The carination on I Br 1 and 2 very 

 slight and indistinct. Arms X, 32 mm. Syzygies: 3 + 4,-9 + 10, 13+14 

 etc. with an interval of 3 oblique articulations.

The description e\idcntly coi'i'esponds on the whole to A. 11. 

 Claek's (lesci'iption of Antrdoii tliclis whicii is a young form of N. 'iiiiiUi- 

 color, A characteristic in which s[)ecimen 1 differs from both the 

 Claekian descriptions, is a slight mcdio-dorsal carination of the radials 

 and the I Br series. 



Possibly the original Clarkian opinion that ('akmielra and Neo- 

 melra ought to be united in one genus is the right one. Tiie diffe- 

 rence between the two genera, namely that I\ and P.^ in Cakmietra 

 are about as long as the following pinnules, in Neometra considerably 

 hinger, scarcely holds good (see the comparison given l)clow).
