ADDENDA — SCHULTZ 151 



spots. E. fuscoguttatus is more dark spotted dorsally on head and 

 body than ventrally, and sometimes the ventral surface of the abdomen 

 is unspotted or nearly so; the mottled and barred color pattern may 

 or may not cover the abdomen. In E. horridus the abdomen may 

 be brown, but in addition it is profusely brown spotted. The paired 

 blackish blotch on the snout in the premaxillary groove in E. horridus 

 is absent in E. juscoguttatus . 



Fowler and Bean (U.S. Nat. Mus. Bull. 100, vol. 10, p. 287, fig. 22, 

 1930) noted these differences as they stated "our materials seem to 

 show two fairly constant variations in color. In the first the throat 

 is with cross bars, the dark blotch on the caudal peduncle small and 

 the spots on the body relatively small. The second variation is with- 

 out cross bars, spot on caudal peduncle very large and spots on body 

 large and hexagonal." 



Remarks. — Randall (p. 48) states that E. juscoguttatus and E. 

 horridus may be distinguished by means of the number of gill rakers 

 and the differences in greatest depth. I agree with the former state- 

 ment, but in regard to the latter, my measurements of 10 specimens 

 of E. horridus show that the depth is 31 to 35 percent of the standard 

 length and that of E. juscoguttatus ranges from 31 to 40 percent. The 

 deeper bodied specimens are the largest ones as is generally true for 

 other serranids.

Dr. J. L. B. Smith (Ann. Mag. Nat. Hist., ser. 12, vol. 7, p. 866, 

 fig. 1, pi. 7, fig. B, 1954) described as new Chorististium africanum, 

 from 4 specimens, one each from Pinda, Pemba, Zanzibar, and Teko- 

 mazi islands. In this same paper Dr. Smith records the occurrence of 

 "Chorististium susumi Jordan and Seale" from several localities off 

 the east African coast. However, Smith's plate 27, fig. C, shows the 

 color pattern of Chorististium lineata (Schultz) and not that of 

 C. susumi. 1 conclude therefore that C. lineata is the species that 

 Smith has collected, not C. susumi.

Dr. Bohlke (Notulae Naturae, Philadelphia, no. 291, pp. 1-7, pi. 1, 

 1956) has pointed out that I overlooked one of the almost embedded 

 dorsal spines in Ypsigramma lineata Schultz and that Chorististium 

 ruhrum (Poey) is scaled over between dorsal fins as is Y. lineata. He 

 concludes that Ypsigramma Schultz is a synonym of Chorististium 

 Gill, with which I fully agree. Therefore, the generic name Choristis- 

 tium must be transferred to the 16 section of the key on p. 373, and 

 the 2a section of the key must take the next available generic name, 

 Pikea Steindachner.
