Macrocceloma eutheca (Stimpson). 
Pericera eutheca Stimpson, Bull. Mus. Comp. Zool., 11, p. 112, 1870. A. Milne Edwards, 
Miss. Sci. au Mexique, pt. 5, 1, pp. 58, 200, pl. xv A, fig. 1, 1873. Aurivillius, K. Sv.

Macroceloma eutheca Miers, Challenger Rept., Zool., Xv11, pp. 80, 82, 1886. 
To this species I have referred an adult male from off Havana, lat. 23° 
10’ 51” N., long. 82° 19’ 03” W., 163 fath., white and brown. cor: il, 
station 2323, U. S. Fish Commission, 1885 (9492); also a young etait 
from near Aspinwall, lat. 9° 32’ N., long. 79° 54/30” W., 34 fath., broken 
shells, station 2146, 1884 (7780); and a young female from lat. 23° 10/36” 
N., long. 82° 20/ 20" W., 122 fath., coral, station 2168 (7756). 
The adult male differs from Stimpson’s description in its slightly 
narrower carapace, longer rostrum with divergent horns, and in the 
presence of tubercles instead of spines on the gastric region. A. 
Milne Edwards figures, without remark, a specimen which he calls 
eutheca, although it is much narrower than the one in question, the pos- 
terior half of the carapace is much rounded, and the rostral horns are 
separated by a triangular interspace. 
- The specimen under examination has the carapace very much nar- 
rower posteriorly than in MZ. concava Miers (Op. cit., p. 81, pl. X, fig. 2),
