Pandalus jordani Rathbun, 1902 (Fig. 25 F) Pandalus jordani Rathbun, 1902a: 900; 1904: 40. — Schmitt 1921: 41, pl. 14, fig. 1. — Kozloff 1974: 163. — Word & Charwat 1976: 183. — Butler 1980: 133, pl. 4D. — Wicksten 1989b: 313. Diagnosis. Body slender, surface smooth. Rostrum as long as carapace, with 4–17 dorsal spines, teeth; 7–10 ventral teeth, apex acute or bifid. Eye large. Stylocerite of first antennae short, both flagella longer than carapace. Length of scaphocerite of second antenna about half length of rostrum length, lateral tooth, blade equal; basicerite with moderate upper lateral, strong lower spines, flagellum longer than body. Third maxilliped with antepenultimate segment having slight lamina, epipod present. Pereopods 1–4 with epipods. Pereopod 1 slender, proximal end of merus with slight lamina. Pereopods 2 unequal, left longer, with 58–62 articles; right shorter, with 19–22 articles. Pereopods 3–5 slender, with slender dactyls bearing 4–7 spinules, propodus with 8–23 spinules, carpus with 2 or 3 spines, merus with 7–11 spines, ischium with 0 or 1 spine, decreasing in number from pereopod 3–5. Abdominal somite 3 with dorsal posterior part compressed, with carina. Posterolateral margin of pleuron 4 with moderate ventral point, pleuron of somite 5 with strong posterolateral point. Somite 6 shorter than telson. Telson with 8–13 pairs dorsolateral spines, 3 pairs distal spines. Male total length to 125 mm, female to 175 mm. Color in life. Fine red dots on translucent grayish background. Proximal part of antennal flagellum pale pink (Butler 1980). Habitat and depth. Offshore green mud or mixed sand, 36–457 m. Range. Iliuliuk Harbor, Unalaska I. to San Nicolas I., California. Type locality off Santa Cruz I., California. Remarks. Pandalus jordani is fished from Vancouver I. to Morro Bay, California, but the highest population density is off central Oregon. Catches are highest at 110– 183 m. : Published as part of Wicksten, Mary K., 2012, Decapod Crustacea of the Californian and Oregonian Zoogeographic Provinces 3371, pp. 1-307 in Zootaxa 3371 on page 101 : {"references": ["Rathbun, M.
