PLATE 7. 
Photographs of Cryptolithus tessellatus Green, made by C. E. Beecher. 
Fig. 1. — Specimen 233. The best preserved individual, the one from which Professor 
Beecher' s drawing (text fig. 45) was made, and which served as the principal basis for the 
restoration (text fig. 20). Note the long, backward directed antennules, the abrupt back- 
ward turn of the outer portions of the endopodites, the way in which the exopodites extend 
beyond the endopodites, and the fact that all are beneath the cover of the dorsal shield. 
The hypostoma is turned entirely around, x 10.9. 
Fig. 2. — Specimen 235. Half of the thorax and pygidium, with the appendages re- 
vealed from the ventral side. Note the abrupt manner in which the outer portions of the 
endopodites are turned backward. See also pi. 8, fig. 3, and pi. 9, fig. 1 (right half), x 14.45. 
Fig. 3. — Specimen 236. Detail from fig. 4, to show the blade-like seta; of the exopo- 
dites and the numerous terminal spines of the endopodites. x 30. 
Fig. 4. — Specimen 236. The appendages of the thorax and pygidium, seen from the 
lower side. Specimen 236 is the right half of the same individual from which specimen 235 
was obtained. Note the interarticular membranes between the segments of the endopodites 
and the blade-like seta; of the exopodites. See also pi. g, fig. 1 (left side), x 19. 
Fig. 5. — Specimen 236. The same specimen, seen from the dorsal side, showing, when 
the test is removed, the long blade-like setae of the exopodites. See also pi. 9, fig. 2 (right 
half), x 19.
