TELLINA PLANISPINOSA. el. testd elongata, attenuatd, 
lateraliter arcuatim flexuosa, solidd, concentrice lirata, 
alba, interruptim et sparsim fusco radiata; latere pos- 
tico acuminato, margine dorsali recto, supra depresso, 
spinis extantibus planatis ornato, valvule dextre infra 
marginem excavato, ad angulum costa lata laminis ex- 
tantibus ornata radiato, valoule sinistre infra margi- 
nem planato, ad angulum laminis spinosis parvis biradi- 
ato, termino oblique truncato, rostrato, margine ventrali 
prope terminum arcuatim concavo ; latere antico sub-

FLAT-SPINED TELLINA. Shell elongated, attenu- 
ated, laterally bent in an arch, solid, concentrically 
ridged, white, interruptedly and sparingly rayed with 
brown; posterior side acuminated, dorsal margin 
straight, depressed above, ornamented with promi- 
nent flat spines, in the right valve hollow under the 
edge, rayed at the angle with a broad rib ornamented 
with prominent laminee, in the left valve flat below 
the edge, with a double ray of small spinous lamin 
at the angle, end obliquely truncated, beaked, ventral 
margin arched, concave near the end; anterior side 
subacuminated, dorsal margin sloped, serrated with

THE 
In four similar species we have the following distinc- 
tions: in Tedlina Antonii the ridges are laminated on the 
posterior flexures of the shell, and have radiating strive be- 
tween them; in Tellina Cumingii there are uoradiating 
striae, and the lamine on the posterior flexures are pro- 
duced into spinous projections; in Zel/ina planispinosa 
these projections are more distinct, and there are also la- 
minar projections on the anterior dorsal edge; in Zedlina 
Deshayesii these latter become also spines, and a single 
row of spines on the posterior side takes the place of the 
broad laminated rib.

| THE GROOVED TELLINA. Shell ovate-subtrigonal, solid, 
compressed, nearly equilateral, yellowish-white, radi- 
ately striated, concentrically ridged, ridges elevated, 
subrugose, more prominent at the sides; posterior 
side acuminated, rostrated, radiately grooved, trun- 
cated at the end, rib sharp, ventral margin ventricose ; 
anterior side subacuminated, umboes acuminated.

Only one or two specimens are known. 

Species 198. (Mus. Cuming in Brit.) 
TELLINA ASPERRIMA. Tel. testd ovatd, solida, compressd, 
alba, roseo radiata, tuberculis spinosis omnino aspe- 
rata; latere postico longiore, angulato, ad terminum 
truncato, margine dorsali declivi, margine ventrali ante 
angulum subcontracto, medio recto; latere antico de- 
clivi, umbonibus parvis, elevatis, acuminatis. 
THE VERY ROUGH TELLINA. Shell ovate, solid, com- 
pressed, white, rayed with pink, roughened in every 
part with spinous tubercles ; posterior side the longer, 
angular, truncated at the end, dorsal margin sloped, 
ventral margin slightly contracted in front of the 
angle, straight in the centre; anterior side sloped, 
umboes small, elevated, acuminated.

Hab. Sual, Isl. Luzon, Philippines. 
In Zellina pulcherrima the anterior side is the longer ; 
in Tellina asperrima, the posterior side. In the former 
the spinous tubercles are only seen at the sides and to 
wards the margin.

subequilaterali, concentricé striatd vel sublevigata, 
undis magnis concentricis versus umbones usque ad 

medium rugatd, valeuld dextra eatus concavd, valvulé
