articulation, flagellum 1-3 jointed, the minute apical excluded. Ter-

Scyphax ornatus, Dana, U.S. Explor. Exped. xiv, Crust. part i, 
p. 734, pl. xlvii, fig. 5, (1853). 
Body elliptic, abdomen not abruptly narrower than thorax. Head 
not shorter than following segment, transversely elliptical, eyes occu- 
pying the whole of the lateral margin. Segments of thorax subequal. 
Abdomen six-jointed, two anterior segments partly concealed by 
thorax, last segment very much narrower than preceding, and widest 
at base. Caudal stylets as long as abdomen, branches little unequal, 
minutely hirsute. Antenne a little longer than half the body. An- 
tenne and feet minutely hirsute. Length 6—10 lines. 
New Zealand ; Bay of Islands; Parua Harbour (Dana). Found in 
the sand, and often seen running on the beach. 
Colour variegated, irregularly spotted with bright yellow-red, 
brownish-red, and jet black, producing a beautiful appearance ; 
antenne colourless, or nearly so. Body quite evenly elliptical, surface 
indistinctly a little spinulous. Posterior angles of thorax acute. Last 
abdominal segment subtriangular, with apex truncate, not more than 
half the width of the preceding. Caudal stylets have the branches 
straight, the base fills up the interval between the last two abdominal 
segments. Legs have second, third, and fourth joints subequal. 
Antenne have last three joints together, (corresponding to flagellum), 
but little longer than the preceding one, and this a little longer 
than the next preceding, the first three about equal in length to last 
three. (D.). 
Dana figures and describes a smaller specimen, found in and upon 
the same beach, which he suspects may be the young of the above. 
The general form is the same. All the specimens obtained were about 
two lines long. The last segment of the abdomen does not project at
