A pair of small tubercles (tb) located dorsolaterally
to anterior margin.
Mouth slightly oblique, lower jaw projecting about 1 mm in front of upper lip; maxilla reaching vertical at rear edge of orbit; lower jaw with band of minute slender teeth, band widening anteriorly, with small conical tooth projecting dorsolaterally
on each side at front of lower jaw, followed by large, curved, retrorse canine posterior to the smaller conical tooth at front of jaw.
All these specimens exhibit a shagreened skin on dorsum with low tubercles dorsolaterally
and posteriorly, tympanic membrane smooth, upper eyelid without tubercles, vocal slits in males, heel bearing a prominent triangular tubercle, and posterior surfaces of thighs with a red longitudinal stripe.
There is some variation in relative development of this pterygiophore in large western Atlantic specimens, but in all those we have examined (including a number of partially articulated skeletons at the AMNH not listed below) it is dorsolaterally
expanded in marked contrast to the slender profile of the bone in eastern Atlantic specimens (Fig.
Abdomen light with striated patterns of pigment laterally and above, particularly dorsolaterally
except for pair of light areas at two-thirds of length, light ventrally but darker laterally, length 5.
Scales large (28 to 29 in lateral line); lower limb of preopercle scaly; one or more dark blotches dorsolaterally
on sides; yellow eye stripes.
Metasoma behind tergite 1 predominantly yellow to brownish yellow, dorsally and dorsolaterally
brown to dark brown (usually only tergite 2 conspicuously brown-marked dorsally).
25 mm) was injected dorsolaterally
behind the head and anterior to the dorsal fin by using a hand-held multishot injector (Northwest Marine Technology, Shaw Island, WA).
Two white sharks were present as well, one of about 4 m and the other a larger animal with a distinctive bite scar on the right side, located dorsolaterally
and posterior to the first dorsal fin.
Cerebral commissure about as long as lateral connectives, cerebral ganglia thus located dorsolaterally
in circumpharyngeal nerve ring.
Gizzard 7 Calciferous 9 9-10, paired glands dorsolaterally
, large, globular Spermathecae 11/12 & 12/13, multiple Characters Tritogenia Tritogenia sulcata var.
The supra-hypandrial sclerite as here defined for Namibimydas and Nothomydas is attached dorsolaterally
to the fused gonocoxite-hypandrial complex.
