PLATE XLII. 
Fig. 1. Coscinasterias (Distolasterias) euplecta. Actinal view of an arm and disk. Type; enlarged nearly 
2 diameters. 
Fig. 2. Same. Abactinal aspect. 
Fig. 3. Same. Young specimen, Xl-83. 
Fig. 4. Same. View of side of arm of a prepared specimen to show arrangement of plates, Xl.83. 
Fig. 5. Zoroaster spinulosus. Actinal aspect of type, Xl-83. 
Fig. 6. Same. View of side of ray to show spinules and radial tubercles, Xl-83. 
PLATE XLII!. 
Fig. 1. Odinia padfica. Abactinal View, slightly less than natural size. 
Fig. 2. Brisinga evermanni. Abactinal surface of an arm which has been partially dried, about Xl- 8. 
Fig. 3. Brisinga panopla. Abactinal aspect of genital region of a ray, Xl.8. 
PLATE XLIV. 
Fig. 1. Brisinga panopla, slightly reduced. 
PLATE XLV. 
Fig. 1. Brisinga alberti, slightly reduced. 
Fig. 2. Same. View of side of a portion of an arm, enlarged about 1.8 diameters. 
Fig. 3. Brisinga panopla. Portion of ray, side view, to show particularly the actinal adambulacral spines 
and costal spinelets, Xl.83. 
Fig. 4. Brisinga evermanni. Actinal surface of ray. Tube feet have been removed, Xl-83. 
PLATE XL VI. 
Fig. 1. Brisinga fragilis. Disk and 3 rays. The disk and upper ray belong to “variation a.” The 
lowest ray is the typical form, while the middle belongs to “variation d,” in which the 
secondary costae, only slightly developed in the typical form, extend across the abactinal 
surface, but do not fuse with the lateral plates. Enlarged about 1.7 diameters. 
Fig. 2. Brisinga alberti. Actinal surface enlarged, showing the curious actinal adambulacral spines near 
disk, Xl-83. 
Fig. 3. Same. Abactinal surface, Xl-83. 
PLATE XLVII. 
Fig. 1. Odinia padfica. Side of a portion of ray, mid-genital region, showing actinal adambulacral 
and first lateral spines, X2. la. Same, from a dried specimen, X3. ad. s., adambulacral 
spines; ad., adambulacral plates; l. s., lateral spines; c. r., costal ridge. 16. Side of ray, 
beyond middle, showing lateral spines, X3. lc. Mouth plates, X4. The lateral process on 
the right is fused with that of the other side of furrrow. Id. Pedicellaria from adambu- 
lacral spine. 
Fig. 2. Brisinga panopla. Side of ray, about 40 mm. from disk, or just beyond the club-shaped actinal 
spines, X3. Lateral spines, fore-shortened. 2a. Adambulacral plates about 40 mm. from 
disk, X4. Many of the spines are shown without pedicellarise. 2b. Adambulacral plates 
at about 65 mm. from tip of arm, X4. 2c. Mouth plates, X5. ad. s., first adambulacral 
spines; am.f., ambulacral furrow; rn. s., marginal spines; rn. s/, furrow spines of mouth plates; 
ms.", actinal spine; sac., sacculus bearing pedicellarige (see 2d). 2d. One of the larger pedicel- 
lariae from a large adambulacral spine. 2e. Twelfth adambulacral spine, X7. 2 f. Seventh 
adambulacral spine, X7. 
Fig. 3. Brisinga evermanni. Side of ray, about 44 mm. from disk, X7. 
Fig. 4. Brisinga alberti. Side of ray, about 40 mm. from disk, X 3. 4a. Pedicellaria from adambu- 
lacral spine near base of ray.
