mostly very short and of oval outline. Approximate distribution 

 of the internal longitudinal vessels. 



Right side: dorsal 10 (34) 11 (28) 8 (30) 9 (14) 7 ventral. 

 Left side: dorsal G (30) 10 (20) 10 (23) 10 (11) 8 ventral. 



Digestive and reproductive organs much as in Styela tinaktae just 

 described. Stomach elongate, with numerous rather irregular plica- 

 tions in its wall. Rectum rather long; margin of anus with numerous 

 long lobes. 



On the right side six tubular more or less sinuous gonads were dis- 

 tinguished, placed in an oblique position more or less parallel to each 

 other. On the left side the gonads were too much broken and dis- 

 placed to satisfactorily determine their number and arrangement. 

 They were evidently fewer than on the right side and were very 

 crooked, irregular in their distribution and more or less branched. 



The specimen (No. 48) (Cat. No. 5931, U.S.N.M.), is from station 

 D5144 (off Jolo Light, 19 fathoms, coral sand, Feb. 15 ; 1908). The 

 writer refers the specimen to Sluiter's species in spite of some dis- 

 crepancies, believing that as Sluiter had but one specimen, and the 

 writer also but one, considerable allowance may reasonably be made 

 for individual variation; and that the combination of a branchial 

 sac with such closely placed vessels and several long tubular gonads 

 on each side of the body is a sufficiently unusual one to justify regard- 

 ing various minor differences that exist as probably due to age or 

 individual variation. Sluiter's specimen was from latitude 8° 23' 

 30" S., longitude 119° 4' 3G" E., 69 meters.

Body rather elongated, tapering anteriorly, flattened from side to 

 side and extended at the posterior end in the case of both of the two 

 specimens into a short broad laterally flattened pedicel by which the 

 animal is attached. Apertures small, obscurely 4-lobed, the branchial 

 terminal, the atrial some distance back on the dorsal side. Test 

 moderately thick, tough, opaque, of a yellowish white color with a 

 pearly luster within and yellowish brown externally; external sur- 

 face very rough and having a few deep furrows, longitudinal ones 

 predominating, in addition to smaller wrinkles and rough depres-
