Judging from the figure and description, I feel inclined to regard 
this so-called species as an A. ceca in which the ocular has 
fused with the second labial; although two specimens are known to 
present the same scutellation, it is not impossible that this is only 
a case of anomaly. Another character put forward for the separation 
of the two forms, viz. the presence of eight anal segments in A. 
cubana, instead of six, asin A. ceca, does not hold good, since the 
specimen described above, and in which the ocular is distinct from 
the labial, has eight.

Premaxillary teeth 7, maxillaries 4-4, mandibulars 7-7. Snout 
rounded, prominent. Rostral moderate, triangular; nasals forming 
a suture behind the rostral; a pair of priefrontals, a pair of frontals 
and a pair of narrow occipitals; the suture between the frontals is 
the longest, then come, in respect to length, the prefrontal suture, 
the parietal, and the nasal; a large temporal, between the frontal 
and the fourth labial; four upper labials, anterior smallest, posterior 
largest; ocular rather large, eye distinct; no infraocular, the ocular 
forming a suture with the second and third labials; mental trape- 
zoid with concave lateral borders, followed by a pentagonal or hep- 
tagonal chin-shield; three lower labials, second very large; two 
large chin-shields on each side. One hundred and eighty to one 
hundred and eighty-eight annuli on the body and fifty-six to fifty- 
nine on the tail; an annulus contains eightcen or twenty dorsal, 
and sixteen or eighteen ventral segments ; the two median ventral 
segments much broader than the others. Lateral line distinct. 
Six anal segments and four praanal pores. Dark purple above,
