Scale is mm. istics of each developmental stage are detailed below: Zoea I (Fig. 2A, 3A). Dorsal, rostral, and lateral spines are well developed. Minute plumose setae arise between the dorsal and lateral spines (Fig. 2A, 3A). The eyes are sessile. The abdomen (Fig. 4A) is composed of a telson and five segments. Segments 2 and 3 have rounded lobes projecting laterally. The fifth segment has lateral extensions which overlap the telson. Each furcal ramus of the telson bears three serrate setae on its inner margin. The medial and lateral margins of each ramus possesses a row of very fine acuminate setae. A thickening overlies the anal opening. The antennule is conical in outline with two long aesthetascs and one short acuminate seta located terminally (Fig. 5A). The antenna has an elongated protopodite with two opposing rows of minute serrations on its distal half. From the proximal portion of the protopodite an acuminate seta projects laterally (Fig. 5F). The mandibles are symmetrical with two incisors located ventrally and a molar process located dorsally (Fig. 6A). Very fine acuminate setae are found on the proximal margin of the coxal and basal endites of the maxillule (Fig. 5K) and the maxilla (Fig. 5P). On the maxilla, these setae are also found on each side of the endopod, and entirely fringing the scaphognathite except where plumose setae are located. The first and second maxilliped are pictured in Figures 7A and 8A respectively, while the third maxilliped has not Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (W
