view, epistome with lateral alae clearly defined and forming ventral 

 articulation sockets for mandible, epistome of this specimen possibly 

 aberrant, having on right side (to left in drawing) a scale of chitin 

 possibly not shed during latest ecdysis; upper lip slightly emarginate; 

 mandibles broad, with flat, apically broad cutting edge, only right 

 mandible with vermiform lacinia mobilis, molar absent; article 1 of 

 mandibular palp with apicomarginal cusp on each extreme, article 3 

 falciform; outer lobes of lower lip scarcely incised; maxillae shown in 

 figures; maxillipedal palp article 2 with small, poorly projecting 

 mediodistal process scarcely extending along article 3, article 4 minute 

 but distinctly articulate; gnathopod 1 scarcely setose, gnathopod 2 

 strongly setose, both minutely chelate; gnathopods and pereopods 

 1 and 2 in preserved condition held under coxae and not visible from 

 lateral view; pereopods 3-5 similar to one another and successively 

 slightly larger (3 broken distally), second articles complexly orna- 

 mented with teeth and lateral ridges; uropods without special features 

 or distinctions but shown in figures; telson short, with medium-sized 

 distal emargination, lateral lobes coniform. 



Female, 29 mm, ET 1003: This specimen differs from the 38 mm 

 female in many ways; grossly it resembles Walker's (1907) figure more 

 strongly than does the 38 mm female because the segmental teeth 

 are longer and seemingly more closely spaced even though slightly 

 fewer in number than those on the 38 mm female. Possibly in adult- 

 hood the teeth do not elongate or thicken proportionally to body 

 growth; however, many of the teeth on the 38 mm female are thicker 

 than those on the 29 mm female. Drawings on two pereonal segments 

 and the urosome seem sufficient to demonstrate these differences 

 (figs. 1/, g). Urosomite 3 resembles Walker's drawing in having 2 

 posterolateral and 2 middorsal teeth. Only the right-sided member of 

 each pair of teeth is shown in the figure herein. Urosomite 3 of the 38 

 mm female has a single large posterolateral tooth as if the pair of 

 teeth in the smaller female had become amalgamated in the larger 

 female. The 29 mm female lacks the supraorbital tooth seen in both 

 the 38 mm female and the 8 mm juvenile. The second articles of 

 pereopods 3-5 are more slender, and the posteroventral cusps on the 

 corners of the pleonal epimera are longer than in the 38 mm female. 

 Article 2 of the maxillipedal palp of the 29 mm female, like Walker's 

 figure, does not have a distinct distomedial process. The eye is fully 

 developed and almost perfectly circular, with all of its ommatidia 

 clearly delineated, whereas in the 38 mm female, the posterior margin 

 of the eye is clouded, presumably with carbonate deposits. 



Female, 37 mm, EW 66-022: This specimen has no supraocular 

 tooth and the dorsolateral cephalic flange is extremely strong. The 

 emargination is especially deep.
