Measurements (mm) of Worker: Head length
1.6 mm; Head width 1.6 mm; Scape length 1.3 mm; Eye length 0.36 mm; Eye width 0.38 mm; Mesosoma length: 2.2 mm; Pronotum width 1 mm; Petiole length 0.2 mm; Petiole height: 0.33 mm; Petiole width 0.4 mm; Post petiole length 0.2 mm; Post petiole width 0.4 mm; Post petiole height: 0.5 mm; Gaster length: 1.60 mm; Body length 8.5 mm; Cephalic index: 100; Scape index 1: 81.25; Scape index 2: 81.25; Petiole index: 60.60; Post petiole index: 40
Twelve linear morphometric traits were measured with a digital calliper to a resolution of one millimetre: 1: snout-vent length (SVL), from the tip of the snout to the rear margin of the cloaca; 2: head length
, from the tip of the snout to the gular fold; 3: maximum head width; 4: head width between the eye orbits; 5: head width at the gular fold; 6: maximum head height; 7: interorbital distance, equivalent to the minimum distance between the eyes; 8: forelimb length from the point of insertion to the tip of the longest finger; 9: hindlimb length from the point of insertion to the tip of the longest toe; 10: axilla-to-groin length; 11: tail length; and 12: trunk length, calculated as SVL minus head length
Qty: 3 st 8)magnetic rod with flexible head length
15" or more.
 The maximum head length
was measured as the maximum antero-posterior diameter by spreading calipers from glabella to irion.
Holotype in micros: Total body length 1348.03; head length
100.63, width 123.39.
(2008) and Ishiyama (1958), were taken: 1) total length (TL); 2) disc length; 3) disc width; 4) tail length; 5) head length
; 6) dorsal snout length; 7) eye diameter; 8) distance between orbits; 9) ventral head length
; 10) ventral snout length; 11) prenasal snout length; 12) distance between nostrils; and 13) distance between 1st gill openings.

In this regard, it is common to use measurements such as body length, body depth, head length
, eye diameter, jaw length of fishes to not only assess fish habitat peculiarities and ecological criteria in water bodies, but also to measure discreteness and relationships among various taxonomic categories .
We measured snout-vent length (to nearest 0.1 cm using a plastic ruler), head width (to nearest 0.01 cm using a digital caliper), and head length
(to nearest 0.01 cm using a digital caliper) of each specimen (one specimen was inadvertently not measured, thus n for measurements is 42).
In this specimen, the snout (139 mm) is slightly shorter that the rest of the head (143 mm) or 49.3% of head length
. All of the other scombrid genera known to occur off California have snout lengths about 21-37% of head length
There is some variance from cooper to cooper on the size of the barrels, but for this section's analysis we are using barrels that are 38 inches by 58 inches, head length
by bilge width, when placed on a two-barrel rack.
The Mean [+ or -] SD of Head Length
and width and also auricular height in Native Fars and Turkman groups are depicted in Table I so that Head Length
and width in Turkmans were more than that of Native Fars males but auricular height in the former was less than the latter.
