A full bibliography and a number of other useful tables are also 
included. D.S 
Jenkins on Labroid Fishes of Hawaii. — In the Bulletin of the 
United States Fish Commission Dr. Oliver Peebles Jenkins, of Stan- 
ford University, gives an account of new species of labroid fishes 
obtained by him and by others in Honolulu in 1889 and later. The 
chief collection was made by Dr. Jenkins and his assistant, Dr. 
George C. Price, under the auspices of De Pauw University. Later, 
both Dr. Jenkins and Dr. Price were called to Stanford University, 
and the original collection of fishes, by far the largest yet made about 
the Hawaiian Islands, was supplemented by others, the principal one 
being made by Dr. Thomas D. Wood, also of Stanford University. 
. In the single group of Labridæ and Scaridæ twenty-two new 
species were obtained. These are described and figured in the 
present paper. These new species are the following : 
Macropharyngodon aguilolo. 
Halichæres iridescens. 
Halichæres lao. 
Hemicoris remedtus. 
Coris lepomis. 
Hemicoris keleipionis. 
Thalassoma pyrrhovinctum. 
Novaculichthys woodi. 
Novaculichthys entargyreus. 
Hemipteronotus umbulatus. 
Iniistius leucozonus. 
Iniistius verater. 
Cheilinus zonurus. 
Pseudocheilinus octotenta. 
Anampses evermanni. 
Calotomus trradians. 
Scarus órunnueus. 
Scarus gilberti. 
Scarus paluca. 
Scarus ahula. 
Scarus miniatus. 
Pseudoscarus jordani. 
This list indicates the extreme richness of the Hawaiian fish fauna, 
its isolation and distinctness as compared with the fauna of the East 
Indies, and the fact that the few collections yet made about Hono- 
lulu have barely touched the wealth of the whole. D. S. J. 
Greene on the Caudal Heart of the Hagfish. — In the American 
Journal of Physiology Dr. Charles Wilson Greene gives his studies on 
the caudal heart in the California hagfish, Po/istotrema stouti. This 
structure was first discovered by Retzius in 1890, who accidentally 
noticed a paired pulsating organ in the tail of the slime eel (Myxine). 
The function of this structure is to drive the blood of the subcuta- 
neous spaces back into the circulatory system. : 
We are pleased that Dr. Greene calls this curious animal by its
