CRUSTACEA. 
Mayer’s paper on the caudal glands and the “ house ” of the Phroni- 
midcB (MT. z. Stat. Neap. i. 1878), is also abstracted, 1. c. p. 719. 
Phronima seclentaria (Forskal) figured; Claus, 1. c. pi. ii. figs. 11-14. 
PhronimopsiSj g. n. Body Zoea-like, head short and high, pleon stout, 
nearly globular, its first two segments soldered together, perion narrow, 
elongated; anterior antennas of the female four-jointed, comparatively 
long; mandibular palpus of the male three-jointed; second pair of gn.a- 
thopods with perfect hand, the five following pairs of thoracic limbs thin, 
long, all with small elongated hands ; five pairs of long styliform uropods, 
their branches nearly as long as the stalk. Only one species from the 
Mediterranean [not named], Claus, 1. c. pp. 5 & 6, pi. i. figs. 1-3. 
Paraphronima, g. n. Body compressed, head square, with vaulted 
vortex, last segment of the thorax only a little narrower and a little 
elongated ; anterior antennae of the female four-jointed, posterior rudi- 
mentary, styliform ; mandibular palpi wanting also in the male ; two an- 
terior pairs of gnathopods short, the first with a little developed hand ; 
three pairs of styliform uropods; four pairs of gill-bags on the third, 
fourth, fifth, and sixth segments of the thorax. P. gracilis, Atlantic, 
and crassipes, Mediterranean, sp. nn., id. 1. c. pp. 6 & 7, pi. i. figs. 4-9, 
pi. ii. fig. 10. 
TyphiD2E. 
Claus {1. c., 52 pp.) subdivides this family, which he now calls a tribe, 
Platyscelid^, into the following 5 families : — 
1. Typhidce. Body broad, abdomen shortened, perfectly bent beneath 
the thorax ; buccal organs broad and short ; femoral plates of 5th 
. and 6th segments of the thorax very broad. 
2. Scelidcc. Body broad, abdomen less shortened, imperfectly bent 
beneath the thorax ; buccal organs lengthened, rostriform; femoral 
plates as in the preceding. 
3. Pronoidce. Body more or less compressed, abdomen large, lengthened, 
half-bent; femoral plates of the 5th segment moderately, those of 
the 6th very much, dilated. 
4. Lycceidce. Body compressed, somewhat like Hyperia, abdomen 
large, lengthened, half-bent; femoral plates of the 5th and 6th 
segments similar, triangular. 
5. Oxycephalidce. Body lengthened, abdomen large, not bent, uropods 
styliform ; femoral plates of segments 5-7, triangular, thin. 
He distinguishes (1. c. No. 3, p. 4) the following genera in the restricted 
family Typhidce : — 
1. Eutyphis, new name for Typhis (Risso, nec Montagu [Montfort]), the 
male = Thyropus (Dana), the female = Dithyrus (Dami) = Platy- 
scelus (Sp. Bate). 
2. PLemityphis, g. n. Distinct from the preceding by the two last joints 
of the hinder antennae being long in the male, and by the deeply- 
notched inner edge of the under lip (paragnaths). 
3. Paratyphis, g. n. First pair of gnathopods without, second with a 
rudimentary hand.
