290 FORAMINIFERA FROM MURRAY ISLAND. 



Spiroloculina elegans new species. (PIate96, figs. la, lb, 2). Test 1.5 times as long as wide, much compressed, 

 peripheral margin broadly rounded, apertural end somewhat exserted, rounded, sutures distinctly 

 depressed, wall ornamented with a regular pattern of elliptical depressions arranged in rows longitudin- 

 ally, the depressions of each row alternating regularly with those of the adjacent rows. Length from 

 0.85 to 1. 15 mm. This species reminds one somewhat of some of the species of the Paris Basin described 

 by Terquem, but seems to be distinct from any of those species. It occurred in some numbers at stations 

 I and 2. It is close to S. foveolata. 



Quinqueloculina bicarinata d'Orbigny. A few specimens at station 3. 



Quinqueloculina bicornis (Walker and Jacob). Rare at station 2. 



Quinqueloculina boueana d'Orbigny. Fairly frequent at stations i and 2. 



Quinqueloculina psirkeri H. B. Brady. Frequent throughout. 



QuinquelocxJina reticulata d'Orbigny. Scattered specimens throughout. 



Triloculina oblonga d'Orbigny. A few specimens at station 2. 



Triloculina circularis d'Orbigny. Frequent at station 2. 



Triloculina tricarinata d'Orbigny. A few specimens at station 2. 



Triloculina bertheliniana H. B. Brady. Specimens of this very rare species occurred at stations 4 and 5. 



Triloculina terquemiana H. B. Brady. Specimens were found at stations 2 and 3. 



Triloculina linneiana d'Orbigny. Few specimens at stations 1 and 2. 



Triloculina striolata new species. (Plate 96, figs. 3a, ■}h, $c). Test 1.5 times as long as wide; peripheral margin 

 distinctly carinate, sutures distinct, slightly depressed; face of the chambers in front view fairly tumid, 

 broad, apertural end but very slightly if at all exserted, the aperture broad, oval, with a rather stout, 

 bifid tooth; surface of the test ornamented with very fine, somewhat broken, obliquely longitudinal 

 striations. Length I mm. A few specimens from station 2. 



Triloculina subgranulata new species. (Plate 96, figs. 4a, 4b, 4c). Test slightly longer than broad, chambers 

 very tumid, sutures much depressed, peripheral margin broadly rounded, apertures hardly exserted 

 aperture broadly rounded, with a simple or occasionally bifid tooth, surface very finely granular. Length 

 0.75 to 0.90 mm. Specimens not rare at station 2 



Peneroplis pertusus (Forskal). The typical form of the species was present at stations I, 2, and 5. 



Peneroplis pertusus (Forskal), var. arietinus (Batsch). Specimens at station 5. 



Peneroplis pertusus (Forskal), var. planatus (Fichtel and Moll). Several specimens from station 2. 



Orbitolites duplex Carpenter. Few specimens from all the stations, some showing the wing-like secondary growth 

 so frequent in this species. Not as common as the following. 



Orbitolites complanata (Lamarck). Frequent at all the stations but the specimens small in size.
